AVG Internet Security on Windows PC

I have an AVG PRO licence on my android device with a subscription that claims I can install AVG internet security on "all my PCs"   That used to be the case until I upgraded the PC to Windows 10.  The upgrade wiped AVG off the PC.  So now I am trying to reinstall it.

I have installed AVG Zen on the PC but when I try to install AVG Internet Security by clicking on PROTECTION on the Zen desktop I get an error message saying I have used an invalid licence number.  The instructions state that I should simply log into my account and i have done this in Zen but the installation of protection never gets that far it always stalls at the licence error message.  I have tried this many times now and have also tried uninstalling and restarting from scratch.  I have tried using the process of sending an email from my android to the PC which worked before windows 10 but doesnt now.  I am about to give up on the whole thing and find a new virus checker but having one more try on this forum. I have also tried several times (around 10) to get through to the live chat support but there is never any connection just the little wheel going round and round.  I refuse to spend £20 on an AVG remote install - it shouldn be this difficult.
