Symptoms

The demo worked fine after the little hotfix. The full version now does not launch.
Steam definitely assumes the game is running for 5 seconds.
But other signs than the play button turning into a stop button are missing.

Reproduction

  1. Enable Proton Hotfix for Anno 117
  2. Download
  3. Install
  4. Start

Hello @Freezer838, err:module:import_dll Library GameInput.dll (which is needed by L"Z:\\home\\max\\.local\\share\\Steam\\steamapps\\common\\Anno 117 - Pax Romana\\Bin\\Win64\\Anno117.exe") not found` looks like the line of interest from your Proton log.

As a side note, Proton Hotfix should not be regularly used unless there's a specific hack in there for an emergent issue with the game. In most cases it's an irregularly updated build of Proton Experimental.

Hi @kisak-valve,
Thank you for taking your time and looking into the issue.
I saw the same error, but the file existed on my file system, so I was puzzled why it was not able to find it. I also did verify the files before.
But what actually did the trick was that I switched from Proton Hotfix to experimental and then verifying again.

Thanks again!
I will close the issue.
Kind regards
