EAC: Untrusted system file

Hi,

Every time I try to start Vermintide 2 in DirectX12 mode, I get an error message from Easy Anti-Cheat regarding an untrusted system file.

The file in question is “dxilconv.dll” located at a quite obscure location on my PC:
C:\ProgramData\Microsoft\Windows\Containers\BaseImages\ some hexadecimal string here \Files\Windows\System32\dxilconv.dll.
This error message is accompanied by the vermintide crash screen with GUID: 8442e78e-044a-49ce-b25b-40cbbde1ac41

My system specs:
Intel Core i7 4770
Geforce 1070
16 GB RAM
Windows 10 Pro, 64bit

What I already tried:

  • Verify integrity of game files via Steam options (everything successfully verified)
  • Repairing EAC with EasyAntiCheat_Setup.exe in the game’s folder
  • sfc /scannow in a windows command prompt (no issues found)
  • DISM /Online /Cleanup-Image /CheckHealth and DISM /Online /Cleanup-Image /ScanHealth in a windows command prompt (no issues found)
  • Rebooting, obviously

Please note that this issue only persists when trying to run the game with DirectX12 on the Official Realm. DirectX12 on the Modded Realm and DirectX11 on any Realm runs fine without error.

Thanks in advance for any help or information.

Hello Flap! Could you please try performing a clean re-installation of your GPU drivers using the instructions here?

Hi Julia, thanks for your reply.
I did a clean reinstall of my GPU drivers as described in your linked instructions, unfortunately it didn’t resolve the issue. I still get the same EAC error message.

That’s unfortunate. Do you have the latest updates for Windows installed?

Yes, the latest Windows updates are installed. It is Windows 10 Version 18.09, and when I manually look for updates via Windows Settings --> Updates & Security, it tells me “You’re up to date”.

If I PM you my email address, would you be willing to send me a copy of the dxilconv DLL?

I can then pop it over to Easy Anti-Cheat who will be able to analyse it and hopefully shed some light on why it’s untrusted.

Alternatively, if you’d rather contact them yourself, you can do so here.

Let me know how you’d like to proceed. :slight_smile:

I’d prefer to send the file to you, so you can forward it to the EAC team. I guess it has more weight or urgency if a corporate customer tries to contact them with that issue instead of a single enduser :wink:
The file has a size of about 1,2 MB, let me know where I can mail it to and what additional kind of information I should add to the mail (if any).
Thanks for your help.

No problem! I’ve PM’d you. :slight_smile:
