Every time i try to launch the game i'm getting a Data Execution Prevention error and crashing back to the launcher. I've tried every single suggestion i've found on these forums. I've yet to find any other posts anywhere of anyone having this particular problem with the game so i'm assuming it's something with my system. Hopefully someone can help.

Windows Vista 64 bit
Intel core I7 2.67
Radeon HD4850 512mb

And here's the crash log:

I've made sure the DEP is on the default setting, and even tried to add Witcher2.exe and Launcher.exe as exceptions but it says they're not compatible.

Any input would be appreciated.

Hey Spine shank,

Did you end up resolving this issue? I have the same problem, which is pretty annoying when i've just sunk $100 into a game and then can't install it. Wanted to support Gog over Steam but now I'm regretting my decision

Where did you install the game?

Hey Abbayarra,

Sorry, to be specific, i haven't used Gog in years, and get this error(see below) when I try load up Gog galaxy. So I can'y even install BG 3
Pretty amateur with IT so any help would be appreciated. I'm running windows 7, so perhaps that may be a factor? Thanks!
