If you can't get it to run, the problem is not CPU speed, and probably not memory management issues. The problem is most likely either (1) drivers, or (2) how the installer manipulates the Windows registry. I've had other programs have problems because of how the installer changed the registry. For example, in some cases, if you don't install in the recommended directory, the registry can't find the program (it hard wires the pointer to a non-existent file in a non-existent registry) and things don't run. These problems are a pain in the ass, but can be overcome. --Scot
