Go to the task manager and make sure none of it's services are running. I would even do it in safe mode, so there is no network connection, and it can't try to look for updates. Then try using revo uninstaller.
Thanks aford10. I will try that as soon as I get back to the office and let you know the outcome. Go figure that someone would wind up with two of the most resource hogging (imho) antivirus packages running on the computer at the same time.
The newer versions of Norton 360 aren't too bad. Not nearly as bad as it used to be. I have a current subscription right now. I won't be renewing it, but that's just because it's not worth the $50-$65 they try to charge.
Ok... so from Safe Mode, when I use Revo uninstaller, it lets me select the McAfee to uninstall and asks me to confirm uninstall, then it throws an error of unable to run the Windows installer. So I tried Revo on another unnecessary driver updating utility and it uninstalled it fine.
I am going to try the Revo in normal mode to see if safe mode was hampering the Windows installer...
