I have installed Parallels Desktop, and while I have been able to use everything that comes with it (ie Internet Explorer, Solitaire) I cannot seem to install programs. I have attempted to install the games "Painkiller" and "Warcraft III." In both cases, the installation is complete, but I am unable to open the program. In the case of "Painkiller", I am prompted to insert the correct CD (there are 3 CDs in the game) but I get the same message no matter what CD I insert. "Warcraft III" gets stuck on the loading screen and will not open.
