We seem to get a request to explain the bug on every second page or so. It is explained 2 posts over yours, here's the short version:
Point Man: i haven't checked this thread in a while. Can someone explain to me what's going on? I installed like 20 games about 2 or 3 days ago... What's this uninstall bug? Should i uninstall all my games and re-download then re-install them? I tried going back a few pages and reading what happened but i'm still confused. Anyone explaining to me what's going on would be really appreciated :).
Windows Vista/7/8 are saving the compatibility setting for every executable in the registry, all in one folder so to speak.
When you de-install a GOG game with the bug, it deletes all that information, not just the settings for the game you de-install.
Nothijng too bad, and you do not have to re-download and install all your games, only if you want to keep all your GOG installers on you hard disk like me and some other people.
