Error message when trying to install VPN

Hello Robin,

I will help you further.

Please let me know the version of Windows operating system in which you are trying to install AVG.

I have bought a subscription for AVG VPN, but when trying to install it I am told either  "Program requires Windows Service Pack 1 or later", or error message "0xe001f946" I'm beginning to wish I'd never parted with my money, as I can't seem to find anything other than FAQs or Forum.
