Folder varies between platforms and game editions, one thing all variants have in common, as far as I known, is that the CHITIN.KEY file should be in the same folder.
Windows Beamdog version path: *BG2EE install folder*\Data\00783\ Windows Steam version path: *Steam library folder*\SteamApps\common\Baldur's Gate II Enhanced Edition\
Yes, I'd like an answer to this question, myself, since I only had other people testing Xan on BG2EE. There's a forum for BG2EE enhanced edition users here: forum.baldursgate.net - it should have an answer for sure.
And folks, if you are BG2EE-familiar and have an answer, please, paste it here and I'll memorize it.
I am not very computer savvy, and when I tried to install this mod to my BG2 enhanced edition (that I just picked up) it had a fatal error. Says "Please run this program in your infinity engine game directory" Fatal Error: Failure (Not a Game Directory)
Could somebody please help me with how I solve this? I did run it for my old version of BG2, and it installed no problem. All the options for language, changing class etc. went through just fine. For trying the enhanced edition it stops at the point the little DOS window pops up, and gives the fatal error message before I can select language.
