Hmm... Not sure if this is the one you're using, but I read the readme for
this one and it said to put the .exe file in the "C:\Program Files\Lionhead Studios\Black & White 2" directory, so hopefully moving the file in and running it from there should work. Of course it also says that is no longer requirement, but I can't think of any other reason why it wouldn't be recognizing it. =\
