To update Euro Truck Simulator 2 from version 1.16.2 to 1.17.1, you can use the official legacy updater or manual patch files. Note that if you are playing the Steam version, your game should update automatically; manual patching is only necessary for "Legacy" non-Steam retail installations. Official Update Method (Recommended)

The most reliable way for non-Steam users to update is through the official SCS Software Online Updater:

Download the updater from the Official Euro Truck Simulator 2 site.

Move the online_updater.exe into the folder where your game is installed (usually near your base.scs file).

Launch the updater and follow the prompts to automatically download and apply the latest compatible patch. Manual Download Sources

If the automated updater doesn't work, you can find specific standalone patch files on reputable archival sites:

Patches Scrolls: Offers direct downloads for the 1.17.1 patch specifically for the retail distribution.

Official Legacy Page: SCS Software maintains a Legacy Updates page where you can download "Patch from any older version" to bring your game up to the final legacy version. Key Changes in Patch 1.17.1

Upgrading to 1.17.1 introduces several major improvements to the simulation: Euro Truck Simulator 2 - 1.17 Update is available now!

5. User Interface & QoL

• Map search (type city name).
• Job filters (cargo type, distance, trailer type).
• Quick Travel (teleport between garages for a fee – before “dev mode” was needed).
• Updated Advisor (shows trailer type & cargo).

Error: "Failed to open file ... base.scs"

Your antivirus (or a mod) might have locked the base game files. Disable real-time protection temporarily during the patch, or verify your game cache via Steam (Properties > Local Files > Verify integrity).

⚠️ Important Notes

| Issue | Details | |-------|---------| | Mod compatibility | Many 1.16.x map/truck mods will break due to trailer system rewrite. | | No convoy mode | 1.17.1 is single-player only (multiplayer was still TruckersMP-only at that time). | | No owned trailers | That came later (1.32). Here you can only temporarily attach/detach job trailers. | | Steam Workshop | 1.17.1 supports Workshop mods (yes – added in 1.17 beta). |
