I have been trying to create a log file for an issue with our installer with the following commands:
msiexec /i \"installer.msi\" /l*v \"log.log\" msiexec /i
If you are using Visual Studio 2008, use capital "/L" for the log option. Lower-case "/l" is ignored.
/L
/l
msiexec /i "installer.msi" /L*v "log.log"
This appears to have been fixed in later versions of msiexec.
msiexec
