Regardless of your default browser if using another one open Internet Explorer and go to Tools/Internet Options/Advanced and click Reset, Apply and OK any prompts. Close and reopen the browser, go to Tools/Manage Add-Ons and re-enable any you need and then try your reactivation.

Now my subscription is activated, but real time scanning is turned off and does not turn on on clicking "Turn on ".
My account says - Licenses: 1(2 in use; overlimit). To comply with the license either - buy 1 additional license or remove your mcafee product from 1 computer or deactivate your software from 1 computer.
Please advice what to do as I can't remove or deactivate software from the only laptop I am using.( I can't understand why Mcafee reads as 2 license in use, whereas I am using the same laptop - only thing that I have formatted it doesn't mean that I am using 2 licenses)
- Please Login into your account by clicking on link below
- Click on subscriptions
- Select the old computer which needs to be deactivated
- Click on deactivate button to deactivate the computer
- Now click on verify subscription and update McAfee.
