I have TFD and I just tried playing RA and when I went to go play I got an error saying rundll32.exe has stopped working (see pic bellow) I have it set to Windows 95 compatibility mode, I messed around with the other options it had but no luck.
I have Windows 7 64bit, AMD Phemon X4 9750 Quad-Core Processor, ATI Radeon HD 4650 1024MB Graphics Card, 8GB RAM, DirectX 11
RA is my 2nd fav C&C game I'd love to play it again.
