Hi Matthias, have you look here if your problem can be solved ? .. :



1. Core_ets2mp.dll Error  ( in the top of the topic )...



If core_ets2mp.dll is not working for whatever reason you can get the above error. Usually it appears when you try to update the multiplayer launcher with the game open.


First, check if ETS2 process is running. If so, end it and try again.

If this doesn't help delete core_ets2mp.dll, re-open launcher and re-download file. Path: C:\ProgramData\TruckersMP


Try run the launcher as an administrator? ( right click on the TruckersMP Launcher )
Have you tried deleting the coreets2mp.dll file and starting the launcher?




There is a Guide & Help section over here for more information :

Dear @Matthias13321,


"Cannot inject core - installation of client failed" error is usually caused by a wrong game path. To solve the issue, please ensure that the game path you have given when installing the TruckersMP launcher is exactly the same as the game path of the Steam version of American Truck Simulator or Euro Truck Simulator 2.

So how to find out the game path of the Steam version of ATS or ETS2?
1. First, go to your Steam library. 
2. Then select either "American Truck Simulator" or "Euro Truck Simulator 2" from the library and right-click on it.
3. Next, select "Properties".
4. Once you have done so, head over to the third tab which is called "Local Files" and select "Browse Local Files" after that.
5. Now, you should be able to see the correct game path - http://prntscr.com/mbe59j.
The path for the Steam version of ETS2 is "C:\Program Files (x86)\Steam\SteamApps\common\Euro Truck Simulator 2" for me, but you must note that yours might be a little different.


Once you are fully aware of the game path, remove the TruckersMP launcher from your PC/laptop and then re-install it. You can follow these steps in order you are not fully aware of how to do so:
1. First, press the Windows Key + R (Win+R) on your keyboard.
2. Then enter "%programdata%" and press Enter (without the quotes, of course).
3. After that, find the folder called "TruckersMP" and delete that folder.
4. Then navigate to "C:\Program Files\" - or something similar - and delete the folder named "TruckersMP Launcher".
5. Once you have done so, go to our website and re-download and install the Launcher with administrator privileges [https://truckersmp.com/download/].
-> When installing the launcher, remember to check that the game path is correct.
6. Open The Launcher with administrator privileges and click "Install Available Updates".

If the solutions above did not help - and if you are still facing the problem for whatever reason, try the following solutions:
- Disable the anti-virus for a minute and ensure that it is not blocking the TruckersMP launcher.
- Try to open Euro Truck Simulator 2 or American Truck Simulator with OpenGL. (Go to your Steam library -> Right-click on the game -> select "Launch With OpenGL".)
- When you open the launcher, try to press "F1". It's a known thing that this solution sometimes work. 


I hope that your problem gets resolved as soon as possible. Have a great day!
