Common problemRuneScapeWindows PC and Mac
Jagex Launcher stuck updating or won't repair
Launcher hangs on an update or fails
The Jagex Launcher sits on "Please wait while an update is applied" or can't be repaired. Jagex says the Launcher may be running twice, or you are using an old installer.
How to fix it
Close both Launcher windows from the system tray, then start it again.
To repair it, delete any old Jagex Launcher installer files you downloaded.
Download the latest installer from the RuneScape or Old School site, run it and choose Repair.
If you get "Could not authenticate", turn off your VPN and try again.
On Mac, if the installer does nothing, turn off Auto Proxy Discovery in Network settings.
