timppu: The replies are not always what I've hoped for, e,g, they dismissed my question about Two Worlds Epic Edition not working in Linux Mint due to dependency error because the game supports Ubuntu, not specifically Mint (Mint is based on Ubuntu), but fair enough I guess...
adamhm: That's not right; Linux Mint is one of GOG's supported distros and has been since the start
I checked my correspondence with the support, and I was wrong: they didn't dismiss me, even though they did claim my version of Linux is not supported.
They were even ready to refund the game. (I didn't want a refund though, I can play it in Windows 7 or 10 if needed).
So, yeah, it was actually much better support than I remembered, but maybe I just wished they would have tried to fix the Linux version, e.g. by adding the missing file into their installer, or remove the integrated WINE which (to my understanding) could have fixed the problem as well.
And now for the life of me, I don't recall if I tried their suggestion about manually installing the missing dependency, albeit I think I had tried it and it just isn't available in the repositories anymore. Here's the reply I got:
Unfortunately your Linux distribution is not supported in this game. Because of this, this system is not listed among the compatible ones on the product page. I apologize for the inconvenience.
You might want to try these recommendations:
1) Please make sure you are running the latest version of the game. You may need to download it again from your GOG library:
https://www.gog.com/account 2) Please update your graphics drivers.
3) Open your default terminal emulator ("Terminal"), and run the following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install wine libpng12-0:i368 libfreetype6:i386
4) Uninstall the game and reinstall it to the default directory, proposed by the installer. DO NOT UNDER ANY CIRCUMSTANCES USE A ROOT TERMINAL OR THE SUDO COMMAND TO RUN THE INSTALLER.
(To uninstall the game, use the uninstall script from the game's installation folder, located by default in '~/GOG Games/<your game>' - double-click it in your usual files browser, or start it from a command line with `./uninstall-<your game>.sh` .)
5) Please navigate to game's installation folder, and try to run the game directly using it's BIN file.
If that didn't help, then maybe you have access to a different PC that meets the system requirements and that you could use to play the game?
If not, I can convert this purchase to wallet funds, that you can use towards buying a different game.
