Downgrading and Upgrading American Truck Simulator Version

 

 

Whenever American Truck Simulator gets an update from SCS you need to downgrade the game version in order to use TruckersMP, because TruckersMP doesn't have support for the latest version right away. How soon TMP gets an update depends on how many changes there are in the new update. On average it takes less than 5 days. In this guide I will explain with text and GIF's how to downgrade ATS to supported version and how to upgrade it after TMP update.

 

                                                                                                                                                                                                                                                                                                                                                     

 

Supported version: 1.30.0.1s

 3. Check first that are there any unsupported DLC mentioned below in the Unsupported DLC section of this guide. You need to uninstall the unsupported DLC before you can install the supported version. Uninstall the unsupported DLC by unticking them in the DLC list.

(Note: Nevada is not unsupported. The GIF is just an example of uninstalling DLC.)

 

 

 4. Right click on American Truck Simulator and open Properties

Upgrading American Truck Simulator Version

The latest version of ATS (1.6.1.9s) is now supported in TruckersMP. Time to hit the road!

There's a new version out for ATS (1.29) along side the New Mexico DLC. Neither of those work in multiplayer yet.
See the downgrading guide, if you wish to play in TMP while the latest version isn't supported.
