Also, the installation of Redistrib 2015 fails, which caused me problems with GOG Galaxy not launching. I've just installed this by 1. Installing GOG using "Run Command" on an XP Bottle 2. Installing Redistrib 2015, it will fail 3. Somehow after the failed installation, it works?!
If you are on linux use minigalaxy instead https://github.com/sharkwouter/minigalaxy . Since it's written in python you can cross compile it to use it with mac os as well. Since Gog games are drm free create a bottle with crossover and run the game exe in there.
If you want to easily install minigalaxy on mac just install the latest version of python for macos https://www.python.org/ftp/python/3.9.1/python-3.9.1-macos11.0.pkg . Once python is installed in a terminal type pip3 install minigalaxy (if pip3 throws an error type pip install minigalaxy but first try pip3). Once pip3 has done its work you can access your library (the game must be purchased on the gog website, minigalaxy can't access the gog store as of now, it will in the future). Minigalaxy installs the games and their dependencies automatically. As of now the client can run the games directly using vanilla wine. I wrote the developer about adding crossover and proton support and he said this feature will be added in the near future. For now to run the games with crossover go to the game folder and run its exe with crossover.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
