i need help, how to install the game.

i just downloaded the v3589 files and than i got to select path for the file in the launcher, but whenever i select v3589 file i get this message "Please, select valid directory!", i tried all folders and i went deep into the folders trying to select the valid direction, and yet didn't work. I searched for solution on forum and some of people said "The launcher can download automatic client" i tried this way and still same problem. i need help with this problem.
