Can't uninstall PC Registry Cleaner off my Windows Vista

I was trying to install CCleaner onto my new Dell laptop with Windows Vista and I accidently installed PC Registry Cleaner instead. Now I can't uninstall it from add/remove programs. Can anyone help me with this. Any info would be very much appreciated.

Go to PC Registry Cleaner folder (Most likely C:\Program Files\PC Registry Cleaner) and check if there' any uninstaller file, something like; uninst.exe or unwise.exe.

If it's the one described by McAfee SiteAdvisor it "may be one of the many rogue" registry cleaners out there. SiteAdvisor info.
