I have today purchased Fallout 2 and installed it on a Toshiba P500 Quad Processor running Windows 7.
The game seems to install with "block" graphics and weird colours. But will not run as it continually sahys must have CD, which is already in the drive.
For example I have both GTR games and they work fine on my XP system, but it wont even load on my Vista System(which is nearly 3 times as powerful!). But I bet that its a technical problem like that!
