Have a new machine that came with a 30 day McAfee. I have two other paid for licenses .
1. Do I need to uninstall the 30 day program before downloading my other license?
2.Should I wait until the 30 day program expires to up date, and do I have to uninstall anything?
That is your perogative of course. Should you decide to do so,yes you will have to go to your Control Panel/Programs and Features/Select your McAfee Products/Remove/Restart. Then follow up with the latest MCPR Tool. Go to your account and Download/Install your software.
To make it quicker you can download/save the MCPR Tool to your Desktop for easy access.
Hope this helped..
