PDXpert client installation diagnostics

For new installations and upgrades

Invalid download file

If your PDXpert installer fails to run, or doesn't uncompress correctly, it's possible that the file has been corrupted during download. Return to the download page to obtain a new copy.

Do not run the installer directly from the download page. When prompted, click the Save As button in your browser, and save the installer to a convenient location on your computer's local hard disk.

After the download is finished, run the installer from the saved location.

Permissions and prerequisites

You should have administrator rights to your computer, and be the only user logged into Windows.

The PDXpert client application requires administrator level permissions to install prerequisites such as the Microsoft .NET Framework. The .NET installer requires administrator permissions to run. If the PDXpert installer doesn't run as expected, first install the required .NET version, and then run the PDXpert client setup.

For new installations only

The PDXpert client will examine your system for its Windows and .NET prerequisites and, if missing, will automatically download and install these from the Microsoft website.

During installation, an error may be displayed or contained in the installer log file: Cannot access a disposed object. Object Name: 'System.Net.HttpWebResponse' or Process returned Message: 0xc8000222.

This error usually indicates that Windows Update has a pending system change, or a bad download of the Microsoft .NET installer. Reboot your computer to finish the Windows Update, separately download and install the current .NET framework, or run the Windows Update troubleshooter.

When your Windows / .NET is fully updated, restart the PDXpert client installer.

For upgrades only

Antivirus blocking error

When upgrading, antivirus software may block the PDXpert installer's service utility UninstallPre8Clients.exe. In the installer log file, the error message often refers to the utility, for example:

  • Invalid payload: UninstallPre8Clients.exe, reason: 0x80070002
  • Application requested retry of package: UninstallPre8Clients.exe, encountered error: 0x80070652
  • Applied execute package: UninstallPre8Clients.exe, result: 0x80070645, restart: None
       Error 0x80070645: Failed to execute EXE package
  • Failed to CreateProcess on path: C:\{path}\UninstallPre8Clients.exe

Temporarily disable the computer's antivirus and re-run the installer.

Windows Installer errors

Errors during upgrades may sometimes occur when Windows Installer loses track of installation history, and sees mismatched information in the system Registry. This mismatch is discovered when the PDXpert client installer attempts to uninstall an earlier release prior to installing the upgrade. A typical error message is The feature you are trying to use is on a network resource that is unavailable. Typically, the reference to a network resource is inaccurate and Use source: pdxpert.client.setup.msi will fail.

Uninstall PDXpert using Windows Control Panel

Manually uninstalling PDXpert may be successful, particularly on newer Windows:

  1. Open the Windows Control Panel
  2. In recent Windows releases, open Programs and Features; in older Windows, open Add or Remove Programs.
  3. Scroll down to the PDXpert PLM item, select it, and click the Uninstall or Remove button.

You can now try to run the PDXpert installer. If the error remains, then you'll need to repair the PDXpert installation using one of the following options.

Option 1: For 64-bit, and possibly 32-bit, Windows

Use the Microsoft Fix It tool to uninstall the previous PDXpert installation.

The web page specifically mentions that the tool "removes bad registry key on 64 bit operating systems". However, the tool can be installed on, and may repair the bad registry key in, 32-bit systems — it's a bit ambiguous. The technique described in the next option is known to be compatible with all x86 and x64 Windows.

There's an Advanced-Download to run on a different or disconnected computer link for saving a local copy of the tool.

Option 2: For all Windows systems

Microsoft Windows Installer Clean Up Utility, msicuu2.exe, was created to remove incorrect Registry data and prepare for a new install. Although it's no longer available from Microsoft, you can find this utility on a trusted IT download site. The tool is compatible with all 32-bit and 64-bit versions of Windows.

  • To install msicuu2.exe, log into Windows using an administrator account. By default, the setup program will install the Windows Installer Clean Up Utility's files to the folder: C:\Program Files\Windows Installer Clean Up (32-bit) or C:\Program Files (x86)\Windows Installer Clean Up (64-bit).
  • On the Start menu, select All Programs, and click on the Windows Install Clean Up shortcut. The window will list all programs that are installed on your computer that use Windows Installer.
  • Select the PDXpert application only.
  • Click the Remove button, which immediately deletes the PDXpert application from the Windows Installer database.
  • After the clean-up, delete all files - but not any folders - that remain in the %ProgramFiles%\PDXpert folder (by default, C:\Program Files\PDXpert).
  • Re-run the PDXpert installer.

If you choose to use the utility, be extremely careful to select only the PDXpert installation for clean-up. You should consider uninstalling the Windows Installer Clean Up Utility after you're done. You'll find the Windows Installer Clean Up Utility entry in the control panel's Programs and Features.

Message: The feature you are trying to use is on a network resource that is unavailable.

The upgrade is blocked because the previous PDXpert release cannot be uninstalled. A component of the setup .msi file has been damaged or deleted (possibly when using the Windows Disk Cleanup utility).

Solution: Run the previous release's installation file (PDXpertSystemSetup.exe or PDXpertClientSetup.exe), and select Repair. Run it again and select Uninstall. After the old release has been uninstalled, install the new release.

Message: One or more errors occurred.

The PDXpert client cannot be upgraded from the PDXpert server.

An error message One or more errors occurred. may be displayed, and the client log file may include an error trace similar to this:

YYYY-MM-DD HH:MM:SS.NNNN [1] Error PDXpert.Client.Program - System.AggregateException: One or more errors occurred. --->

---> (Inner Exception #0) System.Threading.Tasks.TaskCanceledException: A task was canceled.<---

Solution: To install or upgrade the client application (PDXpert.exe), the PDXpert server must deliver a new package of DLLs over TCP port 48084. When this port is blocked by firewall, antivirus or network proxy server, then the client cannot be upgraded. See Client upgrade when IP ports are blocked.

Upgrade errors in Turkish Windows

The PDXpert client may not download new upgrade code when the server's machine name includes Turkish i/ı characters. This is caused by a problem in DNS resolution in Windows. In this case, the PDXpert client application must be updated:

  • Use the server computer's IP address rather than machine name in the download link, or
  • Manually install using the PDXpertClientSetup.exe installer.

You can prevent this problem by naming the server using only ANSI alphanumeric or hyphen characters.

PDXpert client log-in diagnostics

Log into the PDXpert client

Follow the procedure in the Log into PDXpert help topic.

If the Welcome to PDXpert window is displayed repeatedly when the PDXpert client is launched, this may be caused by an invalid user account name or an incorrect password.

If you cannot log into the PDXpert client, then an administrator can verify your account name and clear your password on your user account. If no one can log into the PDXpert client, the default administrator's password can be cleared using the Reset Admin button on the PDXpert Application Server console.

PDXpert newer releases: 8.0 and later

The PDXpert server communicates with the SQL Server database, and each PDXpert client application. The PDXpert client doesn't directly communicate with the SQL Server database.

  • Each computer's firewall and anti-virus (FW/AV) must allow communications on TCP ports 48084 through 48087. It's usually sufficient to set your FW/AV to allow communications between the pdxpert.exe and pdxpertserver.exe applications. Ensure that your AV doesn't override your FW settings (for example, it doesn't change the Inbound connections: Allow setting).
  • If the Welcome to PDXpert dialog is displayed more than once, the PDXpert client is not able to find and connect to the PDXpert Application Server. This is usually because:
    • The log-in account name or password is invalid: Verify that the account credentials are correct.
    • The PDXpert Application Server has not yet been installed: Use the PDXpert System Setup installer.
    • The PDXpert communications service is not started, possibly because the server computer requires a reboot after installation or Windows Update: (1) In the Windows Control Panel > Administrator Tools > Services, select the PDXpert Server service from the list, and then click Restart; or (2) Reboot the computer.
    • The server machine name is incorrect: Try using the server's IP address rather than name on the PDXpert client log-in window.
    • Communication is blocked by a firewall or antivirus software: Try disabling both, start the PDXpert client, and then enable the appropriate permissions.
  • If the Software License Key dialog is displayed, then the PDXpert client is able to communicate with the PDXpert Application Server.

PDXpert older releases: prior to 8.0

Both PDXpert server and client applications communicate with each other, and both directly access the SQL Server database. The server and client go through several steps to establish a working database connection.

  • Each computer's firewall and anti-virus (FW/AV) must allow communications on TCP port 1433 (for SQL Server) and TCP ports 48084 through 48087. It's usually sufficient to set your FW/AV to allow communications between the pdxpert.exe, pdxpertserver.exe and sqlservr.exe applications. Ensure that your AV doesn't override your FW settings (for example, it doesn't change SQL Server's Inbound connections: Allow setting).
  • If the Welcome to PDXpert dialog is displayed more than once, the PDXpert client is not able to find the PDXpert Application Server. This is usually because the log-in account name or password is invalid, the PDXpert Application Server has not yet been installed, the server machine name is incorrect, or communication is blocked by a firewall or antivirus software.
  • If the Software License Key dialog is displayed, then the PDXpert client is able to communicate with the PDXpert Application Server. This does not yet confirm that the client can connect to the SQL Server database.
  • If the PDXpert PLM client application window is displayed, then the PDXpert client is communicating with both the PDXpert Application Server and the SQL Server database.

All systems must have the PDXpert Application Server installed.

Message: The server could not be contacted.

After you've entered your account credentials on the Welcome to PDXpert dialog, you may receive an error that the server could not be contacted, or the database is not available.

  • Firewall and/or anti-virus configuration: The most common source of communication problems is that a firewall and/or anti-virus is blocking communications between the PDXpert PLM client and the PDXpert Server, or between the PDXpert Server and the SQL Server database. Solution: Temporarily disable both the firewall and anti-virus (FW/AV) on both the server and workstation computers. If you can then sign into the PDXpert client, one of the disabled FW/AV components requires reconfiguration to permit communications.
  • Wait for SQL Server to become active: Immediately after the system is installed, it may take a while to start or may fail to start. Solution: Before starting the PDXpert client, wait at least a minute or two for SQL Server to finish its initialization and to construct the PDXpert database. It's often useful to reboot the server computer after SQL Server or the PDXpert Server has been installed.
  • Enable SQL Server's TCP protocol: Immediately after installation, the default configuration of SQL Server has TCP communications disabled. The PDXpert Application Server installer will enable TCP only while it installs SQL Server Express. If another edition of SQL Server was pre-installed before running the PDXpert Application Server installer, then it's possible that the TCP protocol was not enabled. Solution: Enable the SQL Server TCP protocol.

Message: The socket connection has been disposed

To improve performance, the PDXpert client maintains a data cache on the client computer. Each time that the PDXpert client connects to the server, the cache is updated with all changes since the last connection.

The cache is empty when users log into PDXpert for the first time, reset their account settings, or switch to a different database. If the cache is empty, then the server sends a pre-built cache file to the client computer. Although this file is compressed, it can be quite large if the system contains thousands of items.

The socket connection error may occur when a large pre-built cache file is sent over a slow or unreliable network connection.

Solution: Diagnose and fix the network errors to improve speed, reduce latency and eliminate connection drop-outs. Switch to a wired connection.

Work-around: Manually copy the pre-built cache file to the client computer.

This work-around requires PDXpert 10.3.30372.2 or later.

The PDXpert server's data directory has a pre-built cache file: drive:path\Data\Files\DatabaseId. For each user and database, the PDXpert client manages a cache file: %LocalAppData%\PDXpert\Cache\UserId\DatabaseId\Cache.

  1. Get the name of the server's pre-built cache file, and the path to each client cache. Log into a working PDXpert client as an administrator:

    When you open the exported file, you'll see that it has two sections:

    1. The name of the SERVER pre-built cache file on the PDXpert server computer, and
    2. Each user's folder path where the cache file should be saved.
  2. Get the pre-built cache file from the PDXpert server.

    1. Open the PDXpert Application Server and note the current data directory path.

      Data Directory path
    2. Open Windows Explorer and go to the data directory folder. Within the data directory folder, open the \Files folder to view the pre-built cache files.

    3. The exported file created in Step 1 identifies the SERVER pre-built cache file path and file name. The pre-built cache file name is a "guid" (for example, 0ac4e973d8264575a97f97ddeae964d2), with a compressed equivalent (like 0ac4e973d8264575a97f97ddeae964d2.gz).

      Find and copy the pre-built cache files to a USB drive, or to a shared network location that the client computer can access.

  3. Add the pre-built cache file to the client computer.

    1. On the client computer, log into the Windows user profile of the PDXpert user.

      Windows administrators can perform the following steps in the appropriate C:\Users\username\AppData\Local folder.

    2. Create the folders for the pre-built cache file on the client computer.

      1. Using the exported file you created in Step 1, find the user's name and note the related Windows User Profile - Cache Path.

      2. Open Windows Explorer and go to the user's %LocalAppData% folder. Within this folder, open or create the \PDXpert folder and the \Cache subfolder.

        %LocalAppData%\PDXpert\Cache folder

        Open or create the two other subfolders contained in the Windows User Profile - Cache Path.

        %LocalAppData%\PDXpert\Cache\UserId\DatabaseId folder
    3. Copy the pre-built cache file from your USB or shared network location to the last folder in the cache path. (If you copy the compressed pre-built cache file, decompress it with any gzip-compatible application, such as 7-Zip.) Rename the uncompressed pre-built file to Cache, without any file extension.

      %LocalAppData%\PDXpert\Cache\UserId\DatabaseId\Cache file

PDXpert client operation diagnostics

Attaching large or compressed files is extremely slow or fails

Even on high-speed LANs, aggressive or slow antivirus scanning may interfere with file attachments, particularly large or compressed (e.g., .zip, .rar, .iso) files.

Solution: Create a staging directory on the client computer and set the antivirus software to exclude the folder. Before attaching a file to a record, move the file into the excluded folder.

Insufficient Windows system resources

You may see this error when you have many items open within PDXpert, or many other applications open alongside PDXpert. Although this can appear with any version of Windows, it's far more common in 32-bit Windows XP and/or while using a CAD application with many design objects.

Windows resources effect on structure

Solution: This may be cleared by reducing the number of open objects displayed in other applications, or restarting the PDXpert client to reset the allocated system resources.

Odd display of controls and graphic elements

This error occurs when your screen is not scaled as 100% in your Windows screen settings. The problem is that Windows applies scaling factors inconsistently to fonts, images and controls. Button labels, textboxes and icons may be scaled, while bitmaps, buttons and other controls may remain at 100% (96dpi).

Microsoft has indicated that improvements are being gradually added into the .NET Framework. Microsoft .NET Framework 4.5.2 was the first release to address this problem, and is probably installed on your computer via Windows Update.

Partial solution: If you have PDXpert 10 (or later), try upgrading your computer to Microsoft .NET Framework 4.6 or later. Close PDXpert and other .NET applications before upgrading. You may have to restart the computer after you install this update.

Solution: The problem may be fully addressed only by returning to the standard Windows 100% scaling factor:

  1. On the Windows Start menu, select Control Panel.
  2. In the Control Panel window, select Display.
  3. On the panel Make it easier to read what's on your screen, select Smaller - 100% (or similar text)
  4. Restart your computer to reset the screen scaling.

Problem Event Name: CLR20r3

An application error CLR20r3 is usually the result of a damaged Windows .NET Framework component.

  • Check if one of the PDXpert components is damaged:
    1. On the PDXpert client's log-in window, under Options, mark the Reset my account settings checkbox, and log in as normal.
    2. Otherwise: Uninstall and re-install the PDXpert client application to refresh its .NET components.
  • The computer may have failed Windows updates or damaged Windows Update components. See Microsoft's instructions How do I reset Windows Update components?
  • If there are no failed updates, then your current .NET may need to be repaired. See Microsoft's instructions How to repair an existing installation of the.NET Framework

You can search the web for CLR20r3 to get many other ideas for fixing it.

Repeated installations of the PDXpert client

After logging into the PDXpert client, you should be taken immediately to the main user window. If your PDXpert client has a noticeable delay in opening, this may indicate that the user interface .DLL code has been removed by your antivirus software, and is being downloaded again from the server.

On all computers except the server computer, the PDXpert client application is installed in the %LocalAppData%\PDXpert folder.

  • The PDXpert.exe launcher accepts user credentials, connects to the PDXpert server, and creates the application's main user window.
  • Various .DLL assemblies create the main user window where you manage PDXpert system and data.

You can verify whether your antivirus is removing PDXpert's code. Before opening the PDXpert client, examine the current user's %LocalAppData%\PDXpert\Assemblies folder. This folder should contain a folder for the current PDXpert release, and within this should be another folder \bin containing files like Common.Logging.dll or PDXpert.Resources.dll. If folders and files are missing after previously using PDXpert, it's likely that your antivirus is deleting them.

Solution: To address repeated installs/upgrades, configure the client computer's antivirus software:

  1. Whitelist the %LocalAppData%\PDXpert folder contents.

  2. Allow PDXpert to read & write access to the current user's %LocalAppData%\PDXpert folder.

Whitelist user's LocalAppData folder

Repairing an 8.0.23650.533 client installation

If you see an application error after marking the Reset user settings checkbox, then the client application requires re-installation:

  1. Using the Windows Control Panel, uninstall the PDXpert client.
  2. In Windows Explorer, enter the path %LocalAppData% which opens the location similar to C:\Users\username\AppData\Local.
  3. Find and delete the PDXpert folder.

    PDXpert folder at %LocalAppData%
  4. Use the PDXpertClientSetup download link or the PDXpertClientSetup.exe file to install the PDXpert client. A PostInstaller window may display an error message, which you can ignore by closing the window.

Setting the local file cache limit

To increase performance, the PDXpert client maintains a cache of downloaded file attachments, typically in the %LocalAppData%\PDXpert\FileCache folder.

In PDXpert release 9.1 and later, the file cache maximum defaults to 500MB and is saved in the settings.xml file (file path). The file's XML <CacheLimit> tag is in bytes, and can be edited as needed. Increase the value to conserve download bandwidth; decrease the value to conserve client computer disk space.

Window handles pool depleted

If a user opens too many item records, the PDXpert client application can crash. On restarting the client, PDXpert attempts to restore the previous workspace settings and, in re-opening the item records, again crashes.

Solution: On the PDXpert client log-in screen, mark the Reset my account settings checkbox, and then log in as usual. Keep the total number of open PDXpert objects to a manageable size, and close item windows when you've finished using them. More details can be found in Client restart after window handle exhaustion.

PDXpert client error messages

These messages may be displayed on the log-in window, as a pop-up window, or within the client log file.

Message: Access to the path 'C:\Users\...\PDXpert\Assemblies\{guid}' is denied

The path C:\Users\username\AppData\Local\PDXpert\ is where PDXpert maintains its client logs, cache and downloaded assemblies (binary executables). The error is often seen immediately after the PDXpert Application Server updates the PDXpert client code. The antivirus prevents the client from copying the downloaded assemblies into its executables folder.

Solution: Briefly disable the antivirus to confirm that the PDXpert client runs as expected. If successful, then configure the antivirus to permit the PDXpert.exe full permissions to all files and subfolders within the C:\Users\username\AppData\Local\PDXpert\ path.

PDXpert is included in many antivirus publishers' whitelists (AVG, Avira, Bitdefender, etc.). If your antivirus has blocked PDXpert, please advise us of the software and its virus definition version. We will work with the antivirus publisher to update their whitelist.

Message: Attempted to read or write protected memory...at DBROverlayIcon.DBRBackupOverlayIcon...

You'll probably see this error only on Dell computers. The source of the problem is the Dell Backup and Recovery (DBR) utility's Windows shell extension. DBR apparently installs an obsolete SQLite 1.x that replaces the shared SQLite 3.x that PDXpert requires.

To restore PDXpert operation:

  1. Uninstall both PDXpert and DBR.
  2. Delete the %LocalAppData%\PDXpert folder to remove PDXpert's SQLite database. This forces PDXpert to rebuild its SQLite cache on start-up.
  3. If DBR is not used, then re-install PDXpert only. If you feel DBR must be used, install the latest DBR version from Dell first, then install PDXpert. DBR and PDXpert may not work well on the same computer.

Message: Could not load file or assembly 'PDXpert.UI'

The following error message is displayed when the "localhost" client application cannot be upgraded.

Could not load file or assembly 'PDXpert.UI, Version={release}' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Could not load file or assembly 'file:///{path}\PDXpert.UI.exe' or one of its dependencies. The system cannot find the file specified.

This is the result of installing the entire PDXpert system (SQL Server database, PDXpert server and PDXpert client), and then redirecting that client to a different server. Although the PDXpert client can attach to a remote server that's using the same release, the client fails when the remote server's release is different.

The PDXpert system installs its "localhost" client into the Windows all users (per-machine) profile. Subsequent PDXpert system updates also update the "localhost" client in the per-machine profile. All other PDXpert clients are installed into the Windows user (per-user) profile; a remote server sends the per-user client what's needed to match the server's release. The error occurs because a remote server's per-user code can't be saved into the localhost client's per-machine profile.

Solution:

  • If you just want to access a remote server, and don't need a full PDXpert system on your workstation:

    1. Uninstall the local PDXpert system.
    2. Install the PDXpert client application.
    3. Enter the remote server's name or IP address when you log in.
  • If the same physical machine must support both a full PDXpert system and allow access to a remote server:

    1. Install a separate copy of the PDXpert client.
    2. Rename this new client's Windows shortcut to something distinctive, such as PDXpert Remote.
    3. When logging into the new client, enter the remote server's name or IP address.
    4. Restore the original PDXpert client log-in to use the localhost server name.
  • If a per-machine client installation (e.g., on a Citrix shared host) is required for accessing a remote server, and the full PDXpert system is not otherwise used, then install the 64-bit machine-profile PDXpert client (PDXpertClientSetupMPx64.msi) that's available on the download web page. If your machine is Windows 32-bit (x86), then use the system install and keep the per-machine client in sync with the remote server by installing/upgrading the same PDXpert system release on both computers.

Message: Font '[fontname]' does not support style '[style]'.

PDXpert relies upon a few standard Microsoft Windows fonts (Arial, Verdana, Tahoma, etc.) and styles (normal, bold, italic). This error indicates that your computer has a corrupted or missing Windows font. An example of this error, Font 'Arial' does not support style 'Italic', indicates that the italic Arial font is not available on your computer.

The problem may be caused by Windows Update KB 2982791. Before trying to fix your fonts, uninstall the affected KB updates as described by Microsoft: http://support.microsoft.com/kb/2982791

Solution: Reinstall the font or copy it from another Windows computer.

  1. Go to your C:\Windows\Fonts directory and find the named font file.

  2. Right-click on the file and select the Copy command. Paste the file to another directory, such as your computer Desktop. Although only one file was copied and pasted, you'll probably see several files, such as arial.ttf, ariblk.ttf and ariali.ttf.

  3. Right-click on each file and select the Install command.

    Install to repair font that does not support style

If the reinstallation doesn't work, copy the font from a different Windows machine that does work and place it into the \Fonts folder.

Finally, if all else fails, you can uninstall, then re-install the font: http://windows.microsoft.com/en-US/windows-vista/Install-or-uninstall-fonts

Message: Login failed for user 'pdxpertuser'.

You may see this error when

  • The server client communication service has been stopped while a client is logged into the system. Solution: Don't stop the PDXpert Application Server's client communication service until all users have logged out of the PDXpert client application.
  • SQL Server is being stretched beyond its ability to handle client requests (for example, if you're using SQL Server Express with more than 10-20 users). Solution: Assess your SQL Server configuration and consider upgrading to a higher-performance edition and/or faster hardware.

Message: Object reference not set to an instance of an object

An occasional file system error or an overly-aggressive anti-virus program may corrupt the client configuration or settings files. You may see the message Object reference not set to an instance of an object during log-in.

A clean reinstall of the PDXpert client replaces any corrupt files. If you are not on your server computer:

  1. Using the Windows Control Panel, uninstall the PDXpert client.
  2. In Windows Explorer, enter the path %LocalAppData% which opens the location similar to C:\Users\username\AppData\Local.
  3. Find and delete the PDXpert folder, if any.

    PDXpert folder at %LocalAppData%
  4. In Windows Explorer, enter the path %AppData% which opens the location similar to C:\Users\username\AppData. Open the Roaming folder.
  5. Find and delete the PDXpert folder, if any.

  6. In Windows Explorer, enter the path %ProgramFiles% which opens the location similar to C:\ProgramFiles.

  7. Find and delete the PDXpert folder, if any.

  8. Use the PDXpertClientSetup download link or the PDXpertClientSetup.exe file to install a new instance of the PDXpert client.

The PDXpert client main window partially loads in Windows XP, but fails before displaying the Item Explorer. The client log file includes this exception:

YYYY-MM-DD HH:MM:SS.ssss [1] Error PDXpert.UI.ClientLoader - at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)

at System.Uri..ctor(String uriString, UriKind uriKind)

at MS.Internal.FontCache.Util..cctor()

This error may be the result of an incorrect registry setting for the Windows XP system folder.

Solution: A recommended solution is:

  1. Start the Registry editor (RegEdit.exe).
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment.
  3. Check that windir has a type of REG_EXPAND_SZ. If not, back up your registry (File | Export...) and then re-create the entry to be:
    • Name: windir
    • Type: REG_EXPAND_SZ
    • Data: %SystemRoot%
  4. Restart Windows XP and verify proper operation.

Message: Session is no longer alive

The PDXpert application server assigns a client session ID when a user logs into the system. The session ID is associated with the logged-in account name on a specific computer. When the server application or PDXpert client no longer communicate, the session is removed.

The session expires when:

  • All session IDs have been canceled while the PDXpert server is upgraded. Solution: Restart the client application. In the future, notify users prior to a system upgrade so they can save their work and exit.

  • The user account is shared between multiple workstations or Windows user profiles (this usage may not comply with the software license policies). Each log-in creates a new session ID for the user account, and invalidates any previous ID assigned to that account. Solution: Assign each person a unique named user account.

  • The connection between the server and the client workstation has been interrupted and cannot be re-established, usually because of poor network reliability. Solution: Diagnose and fix the network errors.

Message: The 'DbProviderFactories' section can only appear once per config file

This is typically the result of having Microsoft Visual Studio installed on the same computer. When Visual Studio is updated (new version or patch), the VS installer may add an empty <DbProviderFactories/> to the machine.config file. There may be several of these files, such as:

  • C:\Windows\Microsoft.NET\Framework\v2.0.50727\Config\Machine.Config
  • C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\Machine.Config
  • C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Config\Machine.Config
  • C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\Machine.Config

Solution: In each .NET machine.config file on your computer, look for the section <system.data>. Remove the empty XML tag <DbProviderFactories/> and save the file.

Message: The dock state is invalid.

If Windows closes unexpectedly while PDXpert is open, the docking panel settings file may be damaged.

Solution: Exit the PDXpert client. Start the client and, on the log-in window, mark the Reset my account settings checkbox, then enter your other log-in details as normal.

Message: The 'Microsoft.xxx.OLEDB.vvv' provider is not registered on the local machine.

On 64-bit Windows, you may see this error when attempting to export data in a Microsoft Access or Excel format. The Microsoft 64-bit OLEDB driver is not installed on your system.

Solution: To obtain the required OLEDB driver, install the 64-bit Microsoft Access Database Engine 2010 Redistributable (AccessDatabaseEngine_x64.exe) which can be downloaded here:

http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=13255

If your system already has the 32-bit version of Microsoft Office installed, then do not proceed with installation.

The OLEDB 64-bit driver installation will likely fail with the following Office installer error:

Error on installing 64-bit OLEDB driver

When you have a 32-bit version of Office, you must either

  • upgrade to the 64-bit version of Microsoft Office, or
  • export using only plain text formats such as comma-delimited (.csv) or tab-delimited (.txt).

Message: The requested service provider could not be loaded or initialized

This is a low-level network Windows Sockets Error message, forwarded through the PDXpert error handler. The client log file includes this exception:

YYYY-MM-DD HH:MM:SS.ssss [1] Error PDXpert.Client.Program - System.Net.Sockets.SocketException (0x80004005): The requested service provider could

    not be loaded or initialized

Verify that your firewall is been configured to allow communications between the PDXpert client and server.

If this error is displayed without the PDXpert client log-in window displayed, then it's possible that the system network configuration is corrupt. (As an additional clue, this problem may be related to recent unusual antivirus activity.)

While network-related analysis is best left to your IT staff, you can try the following:

  1. Close all applications, as well as any Internet Explorer and Windows Explorer sessions that are open.
  2. Open a command line prompt and type inetcpl.cpl and wait for the Internet Properties window to open.
  3. Click on the Advanced tab, and then click on the Reset... button.
  4. In the Reset Internet Explorer Settings dialog box, click the Reset button.
  5. When the reset is complete, close these windows and restart your computer.

Message: The type initializer for '{shared .NET component}' threw an exception.

Many applications rely on shared components in the Windows .NET global assembly cache ("GAC"). The error may be caused by a corrupted shared component, bad installation or .NET configuration error.

For example, the open source SQLite database is shared by PDXpert, Chrome, Firefox, iTunes, Skype and many other applications:

The type initializer for 'System.Data.SQLite.SQLiteFactory' threw an exception.

  1. Reinstall PDXpert or other recently-installed or recently-upgraded applications. Examine the computer's install/upgrade history to determine which software requires reinstallation.

  2. Repair the .NET installation:
