Basically install gets stuck at 2% and then fails with the error message "Installation Failed (E#)." with description "Failed to Connect to GOG Servers".

Now, I am a developer so I know to first try things on your end before going to support so I installed Alone in the Dark and Indiana Jones Fate of Atlantis to test the actual connection from GOG Galaxy to the servers is OK and indeed they installed fine.

Is there anything special that needs to be done to be able to install this old game ? I'm guessing either the files were taking down from the servers / moved or there's a specific file or config this particular installation is checking / trying to find in the background and not able to.

Thanks to whoever sees / replies to this !

P.S: I've tried the Browser download from gog.com/account and getting this API response :

{
"error": "invalid_licence",
"error_description": "User #49134234696670310 does not have the license for product #1207658701."
