Well I figured by looking at the system requirements, and looking at his system specs (a stretch I know). Like a GPU supporting directx 9c with 512MB of memory is required. And he had the Intel Chipset Express 945 graphics, which does not meet that, and wants to install a Geforce GO 7300 which A. Is not going to happen, and B.Does not have 512MB of ram.
There's also the convenient error message that says "hey your graphics card doesn't have the necessary hardware to run this"
