Patch 126.96.36.199 was just released, and should be available now.
Below is a link to the documentation of this patch:
"Added AVG 2013 support for Windows 10. (IP-1658/ATTWO-1067)"
R9.1 does not include AVG2013 though right?
It should now be available on 9.1 with this referenced patch applied.
That does mean 9.1 will use AVG 2013 for all versions of Windows.
The patch release also included some of the KAV fixes (database definitions issue / licensing issues) that have been present in 9.2, however, I am unsure if KES/AVG profile issue will impact 9.1.
I would recommend creating a support ticket to get confirmation.
