Installing Solver
 

I am trying to install solver on office 2003. I already have MS Office 2003
installed on my pc but when i go to the add-ins and click on solver it tells
me it cant find the file for solver. So i insert my MS Office disk and that
tells me it doesn't reconize an earlier version of MS Office so it can't
install. Do I need to un-install 2003 first and then re-install it? Any other
suggestions?
