Hi. i have the very same error as kopiguy above.
tried updating the opensetup.exe but error is encountered --
"Selected settings engine has determined, that your installation state will interfere with the correct loading and saving of settings."
appreciate the assistance here.
Edit: just tried to follow some of the previous tips here (run the opensetup.exe as admin, update driver, etc.) but none seem to still work. whenever i try to "OK/apply" changes to opensetup it only ends up in the error above (there was also no setup.log file found). thanks. (am using Windows7 btw)
