Hello everyone,
first of all a big thank you, for all the work in the background!

I'm trying to start the client from a Linux Mint machine.
The client starts, I can click on a server, it's downloading the dependencies.
After that I get a "Could not join - message": 

"The native game-start supervisor exited (code 25): The native session supervisor is not in its protected startup job"

I didn't find anything for the keywords in the wiki, so I hope someone has a suggestion.

The launcher says it's up to date.
I tried starting it with Steam and Lutris - the message shows up in both cases.

I'm not too much into handling Linux behind the GUI, if the message has something to do with my system, I don't see it by now.

Maybe someone has a suggestion what to do, to get it work?

Thanks in advance :-)

Hi! Since you're running the launcher through Wine/Proton on Linux, please do not use
,
, or run Steam as root. That gives Linux root privileges and is not the same thing as running an application as Administrator inside Windows.
What we need is Windows-side elevation inside the Wine/Proton prefix.
Please fully close Gothic, Steam, and the G1R:MP Launcher. Then open the Wine/Proton Windows Explorer for the same prefix and launch the G1R:MP Launcher from there using Run as Administrator.
For regular Wine, you can open the Windows Explorer with:
If you're using a custom Wine prefix:
Then find the G1R:MP Launcher
, right-click it and choose Run as Administrator. Accept the UAC/elevation prompt if it appears.
If you're using Steam Proton, make sure you do this inside the same Proton prefix/compatdata folder that Gothic and G1R:MP are using. Do not start Gothic manually — only start the G1R:MP Launcher.
If the error still occurs, please send us:

• Code:

  launcher.log
• the newest
  
  Code:

  native-*
  folder from
  
  Code:

  G1RMultiplayer/client/protocol-26/logs
• the newest files from
  
  Code:

  G1RMultiplayer/anticheat/sessions

These files should be inside the Windows user profile in the Wine/Proton prefix, usually under:
Also please tell us which Wine/Proton version you're using, for example Proton Experimental, GE-Proton, or regular Wine.

Thanks for your detailed answer.

If I run the wine explorer and navigate to the executable, I can right click it, but there sadly is no choice for "run as administrator".

As I read in other sources, this could be a bug related to my version of wine.
I try some things, maybe I manage to get the "run as admin" option.

------------------------------------------------------------------------

I got a little step further.
I updated my wine which now says 

When I start the wine explorer and navigate to the .exe, I can successfully right click and run as administrator.

Sadly the error still occurs in the same way.

The launcher.log contains:

Protocol-26:
the session-supervisor-stderr.log conains:

There is also a session-supervisor.stdout.log, which is empty.

The /anticheat/sessions/ folder contains no file.

I also tried to start the "Multiplayer.exe" via the wine explorer with the prefix, the Gothic Remake runs with, it has the same outcome.

Maybe this helps in any way :-)
