Hi ebveryone. How can i install GTAIV on Windows 7? ANd read everytthing befor eposting. I'v tryed copying files into HDD and then install, no luck, but since the files were copied disc is not corrupt. I'v installed GTAIV and played it some time ago on Windows XP, so PC specs not needed except i have latest drivers and Windows 7 7600 RTm 64bit (don;t complain about illegality, it is legal). Tryied installing vcredist from the dvd and reinstalling that thing, no luck either. Installed and reinstalled Windows Live too. No luck installing GTAIV again. The error is Catastrophic Failure, component Grand Theft Auto 4, no other details. The error appears on the start of the installation on some .bbik file from tree letters. And forgot to mention that i must run the setup.exe from GTAIV folder with compatibility mode from Windows XP SP2 or 3. Otherwise getting error that it's not compatibile. And there's lots of people who plays it with Windows 7.
