There is a hardware-related bug with (at least) the GOG.com version of NWN that requires me to rename nwmain.exe to something like nwmain2.exe in order for the game not to crash at startup. However, the Ravenloft game launcher explicitly looks for nwmain.exe, so while it loads the game, the game crashes at startup. As a result, the Ravenloft game launcher is not an option for me.
