I recently upgraded my OS to Windows 7. My previous OS was Windows XP. Doom 3 ran fine while I was using WinXP. When I installed it on Windows 7, it doesn't run at all. I set the "compatibility" to Windows XP and set it to "Run as Administrator" and still it doesn't work.
Does Doom 3 work on Windows 7 or not? If it does work, do I need to install a patch or some other file to make it run under Windows 7?
Exactly how are installing it? Do you have the original cd release or did you purchase an electronic version? Have you gone and applied all patches? With Steam, which is where I purchased my copy, it's already patched to the latest release.
