Hi, I've installed GTR Evolution from DVD a number of times but no luck. There is a bunch of disk activity and it checks the DVD but then fizzles. Race7.exe is on the task list. I have 8GB RAM (only some 2 visible in windows), dual nVidia 8800's in both SLI and as single cards but it makes no difference, and endless amount of disk space. DX9c. It goes as far as running the config tool. I finally got the demo from Steam and it runs though it does not allow me to choose the wheel. But it runs fine. Checking config files and the like and comparing with the demo version does not immediately reveal any difference.
