Can't Uninstall UT3 (HELP!!!)

[RemeberMe]

Thanks. I wonder why 1.3 is all I get from unrealtournament3.com?

1.3 is not the current one. 2.0 is.

I guess uninstalling it doesn't matter because I can now see the patch did install (1.3) but for some reason the game still complains about needing a new patch. Is 1.3 the current one? Why won't it play but still complain even with the newest patch???

Manually delete all the demo and retail installation files, then use a tool like CCleaner to clean up left-overs in the registry and remove the UT3 demo/retail entries from the installed programs list. Reboot your machine, and you should be able to install the retail version.

I first installed UT3 demo then installed the retail version. I now tried to install the patch but it must be installing into the demo version because when I try to play on-line it states I need the patch still. So I went to uninstall the demo but InstallSheild failed with an error 1628: Failed to complete Installation. I even put the retail version disc in and it does the same thing. Also, I can not reinstall the retail version because the option is grayed out. I'm am now completely hosed and can't play the game. HELP!!!!
