I have an attive supscription for my other computers. I want to add another license for my new lap (which has McAfee free for 30 days). Do I need to unistall the version on the laptop before I buy the new license that is connected with my other computers?
It would be wise toi uninstall the trial software via Control Panel > Programs & Features and then run the MCPR cleanup tool and reboot, then install from your online account. You can do all that after you purchase whatever suite you choose.
