When playing the game the wrench does not appear in my hand but the rocket launcher does...bit maddening at begining of game....I can hear the wrench but it does no damage.

I have installed the SHTUP mod on advice of others...really want to play the game as I missed out on this...too busy playing Ultima 7 and Underworld many yrs ago....any ideas?

do not install the game into program files.
