There is a test app which shows whether it ought to run on your machine.

it also picks up problems with your graphics system. Any PC from win2K onwards will run it but it might be very slow and jerky on systems with low graphics specs. But try it. Can you get an old AGP graphics card for it from ebay or something like that ?

The free but limited functionality trial link is here too if you think it might run a bit.
