If that is the case, the OP needs to check and see if his computer, router and ISP are supporting IPv6 
He can test that with this link: http://test-ipv6.com/

Is that the case for sure?
Is Avast the ONLY one denying their software to users for that reason?

avast isn't denying their software to users at all.

To keep it really simple:
If the request is IPV4 and the server is set to only accept IPV6, there a problem.
The server will not understand what is asked.
And of course the other way around is the same.

It is like two people trying to talk to each other while each only speaks a language that the other don't understand.

Two different OSs (XP Mode and Win 7) tested on "connection 1" (the one that has no problems in downloading the files) and "connection 2" (the one has problems in downloading the files).

"connection 1" and "connection 2" provide EXACTLY the same results on http://test-ipv6.com/ ...

bruce_b, Eddy, my point currently still holds (despite it is clear that you don't like this): Avast simply needs to fix this one.

Instead forcing users to play with DNSs, routers, IPv4 vs. IPv6 and other stuff like that, Avast simply needs to provide software which works like all the other software do (and like it was in their version 12); that is WITHOUT tweaking ANY of that stuff...

You should be setting up your computers and routers for IPv6 anyway. IPv4 is going the way of the dinosaur and sooner or later you will need IPv6 enabled to get to a lot of web sites. There are not that many that use it yet, but if your hardware and ISP support it, you should enable it. I have it enabled on both my Dell Deminsion 8200 P4 1.8Ghz XP PRO SP3 and also on my Toshiab C855 series laptop with Windows 10 Home 64 Bit .. The test results from the IPv6 site I linked to above shows it is fully working through my ISP AT&T U-verse internet here in Apex, NC

Also the latest Avast Free 17.5.2303 doesn't let me properly complete the update procedure since servers.def.vpx and prod-pgm.vpx (and I guess also other files) are not downloaded with the default DNS servers provided by my ISP.
By this point in time (with version 17.1.2286 being released in February 2017) it's really surprising how much Avast does not care about this DNS thingy that they should properly handle.

I have the same problem with servers.def.vpx and prod-pgm.vpx are not downloaded. Is there any solution for this problem? I can't update Avast definitions during last month.
