How to Auto update Laucher

Yes I've been searching. I saw some threads
one problem How do I make it update or even test it update?

EDIT again -.-:My launcher keeps on downloading everything. even if I already have the stuffs on my client

+plus It gets stuck on "please wait while file duplication ........."

sorry for my bad English lol

Edit your patch.xml delete the stuff you don't want them be updated lol.

i guess your files are encrypted which makes the Launcher slow and stuck when loading
try using Nix Zpatchbuilder
