[IN PROGRESS] I can't install it

Hi!

First, I'm spanish, so forgive me if I make some mistakes.

I've been trying to install the launcher recently (windows version) but it give me an advice, "El parámetro no es correcto". I think it's not Antivirus' fault, 'cause I gave permission to the installer. And I've tried to execute it as administrator, but same result.
I'm using W10.

Thanks,
Riuddy.
