I just bought the game yesterday, I installed it, and as once I tried to boot it for the first time I got the message from Microsoft saying that it stopped responding, I looked around the web, tried various tips to get it working, I uninstalled it, reinstalled it, apply some of those same tips, such as the EAX hotfix, eventually I gave up, I tried the 640 x 480 res, windows xp SP2 and run as admin compatibly and it worked once last night, I turn off my computer, go to bed, wake up, try to boot it up and I'm getting the same problem, I checked and the compatibility 640 x 480 res, windows xp SP2 and run as admin and it won't work this time, I've tried loading up the witcher.exe since I try to load it up from the games folder in the vista start up menu and it won't even attempt to load it when I click launch the game in the menu that pops up since I don't get a crashing message or anything. I'm running the patch 1.4.5.1280, The witcher Enhanced Edition, Vista Ultimate 64 bit, and it's definitely not because my hardware isn't powerful enough, I attached a report from PC wizard. Any help is appreciated, I got this game to have some fun for once during spring break and so far all this game which is suppose to be pretty good from what I've heard has been doing nothing but giving me a headache lol.
