Good to know. 👍

I already have the game installer, I just wanted to use the install script from the app.

From what I have seen it is every GOG game. You have to install it manually if you get it from gog-games.com or another piracy site.

It never used to do that before it just made you add the install files yourself. But yea that is probably what it is doing now.

Yes but it is a hassle.
