Patching Failed

My launcher keep saying patching Failed Why?

that may be caused from several reasons.
your anti-virus may be blocking the launcher from patching, or something else.
I remember my launcher didn't complete patching, so I restarted computer, that seemed to work for me.

try turning off your anti-virus so it will run perfectly.

Again patching failed i restarted turned anti virus off patching failed

Did you try adding FGunZ to your exceptions list in your Firewall?

Or just try patching it again when you turn your firewall off
