im trying to uninstall oblivion original so i can install GOTY.....i keep getting error messages saying it wont uninstall from the disc and that the installation was damaged...is there another way to uninstall it because i cant even do it from the control panel either.....

Some uninstallers, like Revo uninstaller let you remove remaining files and registry entries after uninstalling. I found it's useful when normal uninstaller doesn't work well.
