I'm afraid i've run into a problem with it that I don't even know where to begin with. It says I need to check whether War3 is installed (which it is) and if the HKEY_CURRENT_USER install path exists. Should I just reinstall warcraft3?
Hmm, it seems that your WC3 installation is messed. Try reinstalling WC3, and now that I remember, WC3 viewer allows model extraction from MPQ, and it's more independent from the game.
