Well, I did something wrong.
Now nothing works at all.
When I attempt to run the uninstaller, it goes through the motions as if it were performing the action, but when finished it's as if noting were done at all. Running setup again gives me the option to play the game, or "uninstall."
If I choose to "play" the game, either nothing happens at all, or I get a Windows error telling me that GR has encountered a problem and needs to shut down. Then asks me if I want to notify Microsoft of the problem.
I've tried using Windows "Add/Remove Programs" as well as the uninstaller on the disk itself with no difference either way.
I tried removing the registry key using "regedit" and trying it again, but get the same results.
At this point, I believe that I've ruined something to the point where I'll never be able to play the game on this computer ever again.
Which really stinks!
Sigh...
Oh, and I've checked my computer for malware and viruses. Negative for both.
