Microsoft SQL Server installation log files
Microsoft SQL Server creates log files that can help identify installation problems. If you need to send SQL Server log files for diagnosis, collect and save the logs into a single compressed folder.
To obtain the installation logs for Microsoft SQL Server 2008 / 2008R2 / 2012:
Open Windows Explorer, and navigate to this folder: C:\Program Files\Microsoft SQL Server\version\Setup Bootstrap\Log\ where version is 100 or higher.
This \LOG\ folder contains a summary file called Summary.txt, as well as the contents of at least one (and possibly more) matching time-stamped subfolders <YYYYMMDD_HHMMSS>.
Select all of the files & folders with this \LOG\ folder, open the Windows Explorer context menu, and select Send To > Compressed (zipped) folder to create a new folder with a .zip file extension.
