Monitoring the Upgrade

During installation, SQL Server 2005 Setup generates log files for each SQL Server component and stores the log files in the %ProgramFiles%Microsoft SQL Server90Setup BootstrapLOGFiles folder. You can open the log files in Notepad, manually scan them, and search for "Return Value 3" to find any errors. Alternatively, you can use Windows Installer tools such as Wilogutl.exe (http://msdn.microsoft.com/library/en-us/msi/setup/wilogutl_exe.asp) to analyze the log files. The SQL Server 2005 setup also logs messages in the Windows event log.
