Struggling through my first MSI setup / deployment project for a .NET app. I've got files that need to go in folders other than the application folder.

Anyway - it's not working, and found this gem on google groups, showing how to generate a log file of the installation. Of course, the contents of the log file are pretty detailed, sometimes cryptic info.

msiexec /I "TheInstall.msi" /L*V c:\TheInstall.log

(update)
Info on other command line options for MSIEXEC

Notes on how the file version/date comparison works. KB article here
