I am running Windows Vista and installed McAffee Security Center. This program is not working properly and I wish to uninstall it and reinstall. When I attempt to uninstall it, the message you do not have sufficient access to remove this program, see you System Administrator. I attempted to go to the defauly setting using cmd.exe, but to no avail. Please help since this computer is not totally protected at this time. Thank You.

Hi, Thank you for posting! I would suggest boot into Safe Mode and turn off UAC to uninstall McAffee Security Center. If it does not work, you can try to find the uninstaller of the program and double click and "Run as administrator" to check the result. Meanwhile, it is suggested to contact the software manufacture for more accurate information.
