My previous windows 7 went dead and i formatted and installed new one.
Now it is a whole new story with setting up my box "games of windows"'s GTA IV to work again. I have the installed game folder but of course it don't work and probably i need to delete and reinstall.
1. In the game folder there is a file called "revoke licence". Should I use it before deleting the game folder and reinstall the game?
2. So I just reinstall in and see if I have problems with game of windows? Worst case I can use the tool you were talking about to bypass it right?
