First: thank you very much for answering me in such a short time, really thank you very much. ♡♡  

second: I did everything in the video and still nothing, every step until the moment of adding the Game.EXE in JOIPLAY, the name, the version and the icon and then appears this in the screen.

also, this is a new problem. i had played in joiplay without complications in the same device, but i uninstalled the app like a year ago and now that i want to play again, this happens.
