I thought someone may have thought I meant Red Alert 3.
C&C Decade, all the old titles work fine, Red Alert 3 works fine.
I am only having problems with C&C 3 Tiberium Wars.
I had uninstalled this and it was a fresh install of W7 but 64bit instead of 32bit.
When I first installed W7 32bit the same disc would not run, I had to remove a dll file and re-install a new dll file in it's place, but that came up as a dll error.
This error message I am getting is,
Please make sure you have DirectX 9.0 or higher installed. Also verify that your video card meets the minimum requirements, and that you do not have hardware acceleration disabled in the Display control panel.
I am re-installing C&C 3 again, I will also update it...
Update seemed to patch it and get it working, though I am sure my graphics are poorer with this new install of OS and drivers.
