Im using Lenovo Ideapad Z400 Touch complete with windows 8,after i received a new notification about updating to windows 8.1,i got my hands itchy to try out windows 8.1 but after installation it was ok until i noticed my screen brightness cannot be adjusted!so i reboot the whole system and installed windows 8 to its original state but my Mcafee icon disappeared from the desktop.i tried to install again with the ecard but not successful and now my Mcafee internet security becomes a trial version instead.i have a 3 years on my ecard but its not installed on my laptop.im quite new with computers and if anyone can help me resolve this issue would be very much appreciated....please help me! Thanks
Solved! Go to Solution.
When doing major upgrades or downgrades such as 8 to 8.1 or back it's wise to completely uninstall McAfee during the process as it may interfere with the process and will almost certainly become corrupted anyway.
Uninstall McAfee via Control Panel > Programs and Features
Then run the MCPR cleanup tool and reboot
Reinstall from your online account.
