Hi All,I've been looking around for a fix to this but haven't been able to find any answers relating to it, though I've seen a few other people here and there with the same problems, so if I have missed an actual fix, I apologise in advance.The problem is that when the Witcher loads, it works right up until the main menu appears, at which point the mouse cursor is replaced by a large black rectangular box, and what appears to be half a button is present about halfway up the screen on the left that begins somewhere off the screen. The game then promptly crashes to desktop, and doesn't leave any crash logs behind. The "My Documents" folder shows that the Witcher folders have been created, though not populated, both for local and all users.I have the Witcher, original version installed from DVD.I have installed the game to C:\Games\Witcher (to avoid permission issues with Vista / 7 related games). The game was installed under administrator rights via "Run As"I have installed Witcher EE (1.4, with language packs and additional content), also with administrator rights.I have installed the 1.5 patch, also with administrator rights.These files are all known as working as the game has been installed successfully on a WindowsXP build in the past.My machine is an Intel Core2 Duo (Wolfdale)I am running Windows 7 x64 Build 7600, fully up to date.I have 4gig of RamI am using on-board mobo sound - (though I own a CreativeLabs X-Fi, Fatal1ty edition, it's not installed due to other Windows 7 complications in the past - This is a fresh build since removal)I have an nVidia GeForce GTX280 running version 195.62 WHQL drivers, posted 26/11/2009 (Latest non-beta available)Can't get much more simple than that, and I don't have any problems running anything else (ie: Dragon Age Origins, Mass Effect, Dawn of War II, Far Cry 2, Torchlight, etc), non-steam or steam related. (Note: This is NOT the Steam version of the game)I have tried reinstalling the game several times, several ways, (and yes, with AntiVirus turned off etc), and have used Revo Uninstaller / CCleaner to clean up registry hives post uninstall each time. I have also tried running the game at multiple points between patches to see if it would change anything, with the only notable exception being that if I try running it BEFORE installing EE 1.4, I get an instant CTD with the game refusing to load whatsoever, repeating the same CTD post 1.5 install. Oh, and the game DOES recognise registration without problems.Can anyone shed some light?Regards,Subv3rse
