Battle.net launcher errors

Well, that, the launcher of the battle.net games fails, the error in question is that it says to try it in administrator, when I am already, it creates a loop between two updates and does not update any, shadowlads and classic, and sometimes already nor does it detect the games, so you have to restart, but it does the same thing again, I don’t know what it could be, thanks, I don’t know if it happens to anyone currently, and how did you solve it
