Unsupported Game Version



Hi, I was trying play ETS2MP but then it said that "unsupported game version". So I searched it on web and i follow the instructions of solution. I downloanded client from "https://truckersmp.com/download" and installed it. I tried to change BETA Version from steam but it seems it didn't work. So I could take a little help here. Thanks for your advice. (If needed, I can post some screenshots about it)

@Anriandor, thanks for your fast respond. First of all, i did the thing  "NONE-OPT OUT OF ALL BETA PROGRAMS" and other ones. (Just wanted to make sure if it is not 'none' so i tried them all.) Furthermore, I tried that you said starting as administrator and package thing but still same problem. My problem is about downgrading I suppose.

I can't see any announcement here, "https://forum.truckersmp.com/index.php?/forum/12-development-announcements/". 

Should I wait for MP to update?


Last Update: I figured out how to fix it.

1. Go -> C:\ProgramData 

2. Delete TruckersMP

3. Go to your TruckerMP Launcher folder, in my case it is in here C:\Program Files\TruckersMP Launcher, uninstall it.

4. https://truckersmp.com/download download from here again.

5. Let it update client (without wintermod) and you are done.

Hello @Widmore,


did you make sure that you don't participate in any BETA? I.e. "NONE-OPT OUT OF ALL BETA PROGRAMS".


After having done so, please start the downloaded launcher as an administrator. If you downloaded the latest launcher version, follow the install wizard and select the right path to your games. Run the launcher (as an admin) and install the available packages. It should work from then on.


Additionally, here is a guide for all known launcher errors:


I really hope that I did help you - feedback is always appreciated :)


Kind regards ;)
