[QUOTE=cluetrain;14135290]I need to do the same and was about to try Zsoft as it says that it lets you do a before and after scan of files / directories and registry and then compare after you've done the install.
If it works like I hope I'll post. The only other program I've found which is no longer free so you'd have to find an earlier version is called Regview and it does exactly what you want - I just didn't want to buy it but here's the link to where it is now

Zsoft Uninstaller will do what you want. Go to help and look up advanced uses and look for "analyze an installation" -------clutrain
