I recently rolled back to Windows 7 Professional after upgrading to Windows 10, using to 'Go Back to Windows 7' option in Windows 10.
Since then, whenever Windows 7 starts, AVG Antivirus (Free Edition, version 16.91.7688) would say : "Because you've upgraded the system, reinstall is required. "
When I click on 'Reinstall', it would go online and download a good 55 MB or so. After that, while trying to install, it would ask 'Repair' or 'Uninstall'.
When 'Uninstall' is chosen, after a while, it would come up with the message : 'Uninstallation failed. Description : General Error. 0x064C. Error code 0xC007064C'.
Similar message for a repair attempt as well. Since I am on a free version, I can't even post this on their forum or avail the option of 'have someone install it for you' which they provide with the error message. Why can't things exit graciously ?!
AVG Virus Definitions Update go through fine and I am uptodate.
I do have a Clonezilla dump of the Windows 7 partition, before the upgrade. I am wondering whether I would have to restore it for the sake of a simple antivirus installation issue.

Can you delete the programm the old fashioned way via Control-Panel - Software/Programms or do you receive the same error? Have you tried the official AVG-Remover?

SE rocks! May I request you to put your comment as an answer, so that I can mark it as a correct answer for the benefit of posterity ? – Whirl Mind – 2016-08-04T14:31:03.970
@benjaminS Please see WhirlMind's response asking you to add your commented suggestion as an answer for acceptance since that worked to resolve the issue. – Pimp Juice IT – 2016-08-04T17:05:59.250
