Namur: Try bypassing the launcher. Go to the game folder and in the "bin" subfolder start the game using the file "witcher2.exe"
If you need to change your settings use the file "configurator.exe" (also in the "bin" folder)
I've tried that but I get a very similar result. The game never doesn't start although there is no wolf picture on the screen. Its not really that the launcher is failing its that for some reason the game its self isn't starting :( .
I've also since taken out my dvd copy and installed that and after all the patches have gone through it gives me the same result. Guess I'm going to try again from the dvd without any patches and see if that works any better.
Edit:
Ok well I have it working but not the base W2 enhanced or the 3.2 patch but with the 3.1 patch alone it seems to work... Who knows whats going wrong with the other states. It's working and hopefully 3.2 doesn't have any serious fixes.
Thanks for trying to help Namur.
Edit: and it crashes a lot V.V sigh.
