Lack of an official seal of approval from Bethesda hasn't stopped those of us who use it. What exactly does Fallout 3 do, if you run fallout3.exe? If it starts, but crashes later, you may need to edit your ini for a quad (google, "fallout 3 quadcore fix"). If it doesn't start at all, but the patch applied successfully, I don't know...maybe try upgrading video drivers? It seems to start for like a half second. then shuts down. I don't even really get any of the logos. I just hear the beginning of the music on a black screen and then it minimizies and I get Fallout 3 has stopped working.
