I just upgraded from 2009 to 2010 for the 1-3 PCs license -- awesome price!. I removed the old version prior to running the dmsetup tool and also ran a registry cleaner after removing and rebooting. The installation wnet smooth and install all of the needed tools. Now when I click on the ico on desktop or from the pull down menus to run McAffes Total Protection. Nothing happens. I am running on Windows XP Pro SP3. I also ran the latest virtual technician and found no fault.
The issue is registry leftovers from previous McAfee 2009. The unistaller fails to COMPLETELY remove, registry keys. This is UNACCEPABLE!. I had to manually go to the registry and remove (when possible) all/any registry entry/ies with the mcaffee word.
AGAIN...THIS IS UNACCEPTABLE!
