Did you still need to use protontricks to add .net to the prefix? I've installed GE-Proton 25 but I'm getting the same installer message as before
Try dotnetdesktop6, that worked for me. Turns out it needs version 6.
Don't run the game fullscreen in Desktop mode though, there's no way to quit 😅
yep, ended up figuring out the same things you did! the only thing now is that i can’t seem to get it to run again after closing it. need to delete the prefix and reinstall .net each time.
