All of a sudden Fallout3 refuses to even install. The other day I decided to re-install Fallout3 and play it once again. At that time I was using the same Windows XP setup, and hardware setup that I have been using since the day I bought Fallout3. There had been no system changes made of any kind. The game seemed to install perfectly as always, and I set my options to the ones I always use. Anyway, to make a long story short, when I launched the game, it started to load and then crashed to the desktop. I bought the game within days of it's initial release, and am installing off that same original retail disk. I didn't even have a chance to patch the game. So I un-installed it, rebooted, re-installed, and tried patching to the first official patch before trying to run the game. The 1.0.015 patch began to install, but before it finished, it tried to run the game, and everything crashed. As I was planning to upgrade to Windows 7 on the new system I have coming, I decided to wipe everything off the primary hard drive where I was trying to install Fallout, I installed Windows 7, did all the various driver installation (motherboard, video,sound, etc), and then installed Fallout no patches or mods at this pint, just the original version off the retail disk. It installed, but once again, as soon as I tried to run it, it crashed. As I said, this is the original retail box version, not a digital download version, not some questionable downloaded copy. I have never had any problem like this at any other time in the past, and as I said, prior to installing Windows 7 my system was 100% identical to the setup which has always worked without the slightest problem in the past.
