So i just bought GTA IV and guess what. Every time I put in the disc (disc 1) to start it up, it opens the "Grand Theft Auto IV setup", which tells me "Welcome to the installation process. GTA IV requires the installation of software" etc..
So I click "accept", and the setup screen minimizes. It then automatically pops back up, and it's the same exact setup screen!
Tell me what can i do to fix this and play gta IV

Regards Paulie.
