Yes, the launcher is v1.5.1 and I have been updating it, but it still gives me the same error message.
As for the file location, I don't know if I should keep the file in the path that it's in, or reinstall it on a different path...
I have Trend Micro and I've been putting the files in the exception list every time I install the game.
Sometimes it interrupts, but it's okay afterwards.
