In this article, we'll guide you through common problems and provide effective solutions to get you back in game as soon as possible.
I get the error "Could not authenticate" when loading up the Jagex launcher
When attempting to load the launcher, you may receive this error:
This error message is usually associated with using a VPN when attempting to launch the Jagex Launcher.
Please try disabling your VPN before launching the Jagex launcher to resolve the issue.
My Launcher is stuck on ‘Please wait while an update is applied.’
It's possible the Launcher is running twice on the same machine. To fix this close both Launchers (from the system tray) and then restart to re-apply the update.
Why am I asked to log in to the game after running through the Launcher?
Ensure that both the Jagex Launcher and the game client are running with consistent permissions, preferably as your normal operating system user and not as an Administrator.
Why are files being added to my desktop when I open the Launcher?
This happens when the "CTRL" or "CMD" (⌘) button is being held down when the Launcher is being opened. To prevent this from happening, please ensure that no keys are being pressed on the keyboard when you open the Jagex Launcher.
The Jagex Launcher installer presents a "Timeout waiting for window to load" error message
On some Windows 10 (and below) computers, you may need Internet Explorer 11 installed on your Windows PC to run the Jagex Launcher Installer, even if you don't use Internet Explorer as your main browser.
The Jagex Launcher installer isn't working on Mac
If the installer won't run, and isn't giving you an error then you may have Auto Proxy Discovery enabled. To resolve this issue you can disable this:
- Choose Apple menu
- Then System Settings
- Next click Network in the sidebar,
- Select a network service on the right,
- Click Details
- Finally click Proxies
From here you should be able to disable Auto Proxy Discovery, if you're having trouble you can check out Apple's own article on Changing proxy settings on Mac.
The Jagex Launcher won't launch and I'm being prompted to install Rosetta:
The Jagex Launcher is currently an Intel-based application and compatibility for this is due to end with the release of macOS 28 in 2027. If the Jagex Launcher fails to launch and you're prompted to install Rosetta, you'll need to install this before continuing.
- When the prompt appears, select Install (you may be asked for your Mac password or Touch ID to confirm).
- Wait for the installation to finish, this is usually quick and only needs to happen once.
- Relaunch the Jagex Launcher
