I tried installing Myst again on my computer the other day, but neither myst or riven was working, with the same problem. I put in the cd, and when i press install it just shuts down with no further messages. I tried in compability mode too. I even tried downloading realmyst to see if that was working, but i got the exact same problem.

I'm running Windows xp (swedish version) on a pIV 3,4 ghz machine
