I suggest that you contact Customer Service, as they are better suited to assist you with account issues.
https://serice.mcafee.com/webcenter/portal/cp/home/contact Pay no attention to the *Long wait times* as it generally only takes 2-3 minutes. Via Phone/Online Chat being by far the quickest route.
Uninstall that in the normal manner (Control Panel > Programs and Features) then use the MCPR cleanup tool.
Reboot and then reinstall your current subscription from your account web page.
Or you can send a download link from that account page which you could pick up and open on that laptop..
BTW a hint: I find it quickest (& safest) to save the software downloader to my desktop in the machine in question first.
If you do that, once its saved on desktop, right-click it and go to Properties and click Unblock, Apply and OK.
