>I do have Virtual PC (in unopened box). So maybe I will install it too. Although the computer is old, it is about 4 years old so I am not sure it has capacity to work with Virtual PC.

I doubt it will run well on your PC. I tried it on 1.6 Mhz PC with 512MB of AM and it was too slow to be usable. I think it would work if I added at least 256MB of RAM.
