I don't have wine installed on the system at all other than the wine wrapper that comes with the cncnet_1.0_all.deb package. Fresh Install of Linux Mint 19. Yes, installed using Gdebi. I'll keep trying. I really don't get why it works for everyone else but not for me. I spent almost a whole day trying to get it to work lol. When I click the launcher, nothing happens. When I run in terminal, that is the error code that it spits out.
I guess I'll just have to stick to playing it on windows or setting up in wine manually.
EDIT: Dunno if it makes a difference, but was the Version of Mint 19 you tested, the one with the Cinnamon Desktop?
