compdata may be in different install paths on different distros.The user must locate the file within the proton prefix deep inside compdata to specify its full path, this could be challenging for a novice.app id for non-steam games is random, so this path is different in both start ( /home/userX) and in the middle ( compdata/12345689) making it unpredictable / unreproducible between different systems or different adds of non-steam games.The drawbacks of this approach are around lack of portability and user unfriendliness: Target /home/deftdawg/.local/share/Steam/steamapps/compatdata/2475413791/pfx/drive_c/Program Files (x86)/GOG Galaxy/Galax圜lient.exe It is possible to workaround this issue by replacing the Target with an absolute path on the system. replace Target setup_galaxy.exe with C:/Program Files (x86)/GOG Galaxy/Galax圜lient.exe and delete/clear Launch Options.check that compdata with Galax圜lient.exe was created.set Force Steam Play to true in Compatbility.Add Launch Options of /VERYSILENT /NORESTART.

set Target to setup_galaxy.exe (with correct path).Export GOG_GALAXY_OFFLINE_INSTALLER_URL= $(curl -s ' ' | jq -r '.'content'.'windows'.'downloadLink' ' ) # ''Ĭurl -sL $ > setup_galaxy.exe
