When installing pre-XP game, "Could not set up registry entries."
Hello, new here. I wanted to play an older game (Rollercoaster tycoon) on XP, but when I try to install it, the error messages reads: "Could not set up registry entries." Does anyone know how to fix this problem?
get a version of Rollercoaster tycoon that work on xp(there are lots of them). or right click the setup.exe or cd and select properties. look for compatibility mode

Have you accidently delete something? Look here (trial. the better one) and here(free)
If it's a dos game, try DOSBox. It emulates dos pretty well. If not, you'll have to try the compatibility mode. If that doesn't work, you're out of luck. I had to toss 11th Hour because it didn't work with XP.
Thanks for your replies. I know few people who got this game to work with XP.
Instead, I think there is something wrong with my registry. When I download registry mechanic, it says some core files are missing. When I run Ashampoo WinOptimizer, it is able to find orphaned registry files but not delete it. Plus, the original problem of the error message, "Could not set up registry entries"....
