When I delete all of the *.json files, repair EAC, and launch game it let me actually play the prologue but then when I tried to claim challenge rewards I get backend error and kicks me out. So cleared out all of the EAC files did another verify through steam and now I’m back to square 1.
Ok so, you don’t need to worry about the eac_launcher executable. Let’s take that out of the equation and ignore any errors produced by that.
Let’s start clean by:
Remove the ‘Certificates’ directory located here: C:\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\EasyAntiCheat
Then, proceed to repair Easy Anti-Cheat using the EasyAntiCheat_Setup executable located here: C:\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\installers\EasyAntiCheat
Verify integrity via Steam
Then, please launch Vermintide 2 and screenshot any errors displayed.
I tried that as well I just didn’t take screens of it.
On a whim I went on the assumption that maybe the EAC code has an issue resolving nested drives or non-default directory paths, even though I have no issue running other games that run EAC for example Total War:Warhammer2 and BattleFleet Gothic 2.
This is indeed the case; my original Steam install path was c:\games\Steam…
My “C:\games” directory is actually a second nested SSD
I reinstalled Steam using the default directory structure and I’m able to play now.
What is different in the EAC code for Vermintide 2 versus any of my other EAC enabled games that I had no issues with I can’t say.
