I get stuck at multiple points and mainly at 65% with file downloads and then when I start the installation it won’t continue because it won’t fetch the files from the update server that are different length.
Tested on Win 11 Pro and Win 10 Pro, similar, but still different machines, same issue.
I did contacted ISP and Blizzard about that and got nowhere.
ISP says they do not block anything and Blizzard is being Blizzard.
Oh and when I had Battle.Net installed it wasn’t able to fetch updates.
I’ve been seeing the exact same thing this past month, on multiple machines in my household, both with regards to client installation and game updates. I am on a 1Gbit connection and everything else works perfectly.
