How many licences if you have 1 spare go to your account in www.mcafee.com then consumer and log into your account. Install to the new PC.
If you have only 1 licence you remove mcafee as per here .
Make sure you uninstall via windows first this clears the licence and then run the mcpr cleanup tool. Then open your account and reinstall.
or do it this way if you have deactivate option available

Moved to My Account Online.
As Tony says above, just uninstall from the old machine in the normal manner via Control Panel. That will automatically free up a license.
Then go to your online account and install on the new machine from there. The online account exists for all future downloads, the product key can only be used once for the first installation.
thanks a lot , its work
Good luck ;-)
