mutex killer doesn't work in linux (flatpak/steam/proton/wine)

[Daskan]

Any idea how to make it work under Steam-Flatpak with Proton?

Saw some other issue saying to install .net4.5 .. but that didnt changed anything.

Any idea would be helpful! :)

If it doesn't work, chances are that version doesn't support it and it's simply not possible. Every other version of Wine seems to drop or change support for the Windows functions that are required to kill the mutex.

Alternatively, it's all running in different instances, so if you were trying to use Gw2Launcher to specifically kill the mutex (rather than launch GW2), those instances aren't aware of each other, so the mutex doesn't exist from Gw2Launcher's perspective. You don't actually need to kill the mutex, you can just launch GW2 in different instances of Wine. If you were trying to launch through Steam, note Steam itself won't launch a game that is already running.

Installing .net 4.5 is only for UI problems. Wine uses Mono by default, which doesn't render some things properly, most notably the right click menu would be blank.

@Daskan had the same problem, the above quote pointed me in a direction. Check out https://github.com/Iiridayn/gw2-linux-multibox-launcher/blob/main/gw2-alt.sh - let me know if it works for you. Requires you to have installed fuse-overlayfs (to save disk space), xdotool (to wait for launch and change the window title), and setsid (to wait for launch and change the window title).
