solved Cant launch DCS anymore - ERROR_ONCE DX11BACKEND messages in log

[MadMonty]

Hey, after years of flying DCS I am stuck for the first time without having any ideas left.

After DCS update I wanted to launch DCS for downloading the newly purchased KOLA-map. But DCS does not start anymore.

What I did:

Run complete repair

Reinstalled Nvidia drivers

Did Windows scan for any corrupt drivers

Did windows update

Renamed DCS folder in Saved games to "temp"

 

No matter what I do, the log keeps posting the same issues, all linked to ERROR_ONCE DX11BACKEND

 

Any ideas?

Hi, try these steps (you have already done part of them):

 

Also try B.

Got it solved -  thank to the great ED support!

 

It was a bug created by my Arduino Controller (for FFB Joystick). Simply unplugging it from USB and reconnecting it let DCS start again.

 

First time for me (in years) using ED/DCS support and I must admit they are extremly fast and helpful. Great service!
