Ask the Experts / rct2 not working...

Well, I posted this in the whatever forum, but was told it should be here, so...

To start off, rct2 does not run on my computer, and it should (As far as system requirement stuffs are concerned). I have no clue why. It used too, a long time ago, but it does no longer.

If I put in the cd, the autolaunch comes up with the option play, not install. If I click play, it says there was an error launching the game. So, I exit autolaunch and go to setup, try and install it manually. instead of installing, it says uninstall. If I try to uninstall, it starts to uninstall and immediatley finishes (Check for saved games/not not matter). Nothing has changed since uninstall.

Also, LL doesn't work either. It installs and uninstalls fine, but when I try to play, I get an error trapper. Yet RCT original runs fine.

Also, Add/Remove programs RCT2 shows up, even though its not installed. If I try removing, it just goes back to setup and fails to uninstall.

Anyone got any clue whats wrong? Any help would be appreciated. I could always go downstairs to play it, but thats my dads comp. And he gets snippy when I use it. Also I'm to lazy to go down the stairs.
