Use Microsoft Virtual PC, install a pre-made Windows 98 virtual machine, and then install Riven on the virtual machine.

Installation is easy, and it works flawlessly.
I own RealMyst, Myst Masterpiece Edition, Riven and Exile. They all worked fine on XP and Vista. Although, I am having trouble with Riven on Windows 7. It seems to run partially, but I have a few strange screen effects.

No games were ver written explicitly for Windows 2000. Those that do run on it should also run on Windows XP without any problems.
