Hello! First and foremost, thanks for the help.
I get this "Launch error, please, close all games! 3"
I tried everything, including what's included in the pinned post above on the forum (msconfig > services > hide windows services > disable all), and I installed all the resources (DirectX, etc...)
Also tried turning off the antivirus, and also reinstalled the game, and, of course, restarted my computer. Nothing seems to work. I also closed all apps that aren't necessary for Windows.
Do anyone know if I have any other things to try?
