As title, I suddenly cant install the game Test Drive Unlimited. When I put the disk in and installer comes up it just finishes instantly and says "Installation ended The installer was interrupted before Test Drive Unlimited could be completely installed. Your system has not been modified. Please run setup again." I have tried: Another copy of the game, none of them pirated. Running the ISScript that came with dvd. Running both the installer and autorun. The game has always worked for me since 2006, just today it stopped working when I was reinstalling it. My guess is something is wrong with Windows Installer. My specs: GTX 580 Twin Frozr II, i5 2500k, Windows 7 Ultimate 64bit, 8GB RAM.
