I had problems with my Avast Free Antivirus registration having elapsed and being unable renew it, so I uninstalled the program and reinstalled.
Now I can't register the new installation, due to the same reason: "Online content is unavailable." Screenshots attached.
That same problem has been occurring for years now, but previously I had bypassed it via offline registration. But that option is apparently no longer available. How can I register Antivirus now, when it's built in registration feature remains broken?
This is version 18.2.2328 on Windows 8.1 64-bit.
