Failed to Update [red the other threads]

[Heliks]

Good day, 

 

Yesterday I re installed the game after a long flightsim hiatus, ended up with the "Failed to Update" message of doom. 

I then red the past threads and did pretty much everything, from simply deleting the content of "updates", modifying the startup.cfg to include the login and allow for p2p download, check the firewall and add exceptions. 

Nothing works, and I keep getting the same log:

To note, I once had Il2 installed on this computer and I reside in Switzerland. I am out of ideas and seem to have dried up what I could dredge from the online depth.

 

Thanks for your help and cheers!

Advice from support was to disable your antivirus ...

I am afraid to say I did do that too, to no avail.. It also returned the same log.

I am on windows 11 without defender but Avast in place, which has been disabled along with the remaining agents.

I'm having the exact same problem here. (turned off firewall, turned off antivirus, executed as admin, etc.) I went all the way to a fresh install - even to the default folder, just to be sure. (And I was trying between friday to monday as suggested on the game setup and settings FAQ page under "5) What if launcher does not update the game?")

Please give us a quick fix. Or at least include the gamefiles in the installer download so that we can play at least an unpatched version.

I wonder if this is a leftover from the AWS problem this past week?
