Windows 7 compatibility failure SOLVED!! Hi There! I've been running Windows 7 Beta 1 Build 7000 since the release, without any major issues. But now I have a problem that's really annoying, and I just can't seem to fix it. I just bought the game Grand Theft Auto IV and I was happy to finally test it out. But the game doesn't work, well okey, I think and I start to do a little research. After five minutes of searching the net I can conclude that I need to run it under the compatibility mode "Windows Vista". I go back to the dvd-folder and change this in the GTA IV setup.exe, but in the back of my head I suspect that this is not going to work since I've had alot of problems with W7 not working in compatibility modes. And all my expectations were true, it did not work. The message I recieve follows.. "The application failed to initialize properly (0xc0000005). Click OK to terminate the application" This is not the first time this message appears when I try to run a program in compatibility mode. I've tested to combine it with "Run as an Administrator" and I've also tried to run it under other compatibility modes, but still, same message. Please help me out here, so my money wont be a waste. Greetings (or the way we say it in Sweden..) Med VÃƒÂ¤nliga HÃƒÂ¤lsningar Mattias EDIT: I solved the problem by reinstalling my Windows 7 Beta. Now everything works out.
