Symptoms

Game doesn't start, an application window reports that an Adobe AIR installation is required for the game.

Solution

Assure lcms2 and lib32-lcms2 are installed in your system. The bundled Adobe AIR used by the game requires it.

Former Solution

• Download winetricks script, put it on your PATH and set execution permission for it
• Have lcms2 and lib32-lcms2 installed on your system (pacman -S lcms2 lib32-lcms2 on ArchLinux)
• Add a new override for library mscms in the winecfg "Libraries" tab

  WINEPREFIX="/mnt/seagate/Steam/steamapps/compatdata/421120/pfx" \
  WINEARCH=win64 \
  "/mnt/seagate/Steam/steamapps/common/Proton 3.16/dist/bin/wine" winecfg
  

• Use the winetricks script to install Adobe AIR on the Samarost 3's WINE prefix

  WINE="/mnt/seagate/Steam/steamapps/common/Proton 3.16/dist/bin/wine" \
  WINEPREFIX="/mnt/seagate/Steam/steamapps/compatdata/421120/pfx" \
  WINEARCH=win64 \
  winetricks adobeair
  

After installing Adobe AIR successfully on Semarost 3's WINE prefix by using the WINE that comes with Proton, the game runs without issues.

Start with the Symptoms and Solution sections of issue #1888 and review the reported Proton 3.16 behavior on ArchLinux. No source file, test, or entry point is named; a contribution would need a defined Proton-side change and a reproducible test showing that Samorost 3 starts without the Adobe AIR error.
