Jagex Launcher known issues

In this article, we'll guide you through common problems and provide effective solutions to get you back in game as soon as possible.

 

The Launcher failing to boot a game

If you are experiencing trouble with a game, try uninstalling and reinstalling it:

• If you installed the game through the Launcher, click the three dots next to the Play button and then select ‘Uninstall’
• Alternatively, games can be manually uninstalled
  • Windows: Open 'Windows Control Panel' > Uninstall a Program
  • Mac: Find the app in 'Finder' > Drag the app to the Bin

If this doesn't work, or you're repeatedly seeing an error message such as 'The launcher has experienced an error and needs to close' try uninstalling and reinstalling the Launcher itself. Restarting your device or your network can also resolve problems.

 

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.

 

I get a white screen when trying to install the launcher on my Mac

You may see a white screen when using the Jagex Launcher Installer on Mac if you are trying to re-install it after deleting it or if there was a problem with an update. You can resolve this issue by following these steps:

1. Open the terminal from the Finder and input the following command:
   

   rm ~/Library/Application\ Support/Jagex\ Launcher/launcher-mac.production.json

2. Open the Jagex Launcher installer app and install as normal

 

My Mac Launcher doesn't self update

We're aware of an issue with the launcher macOS Ventura, where the launcher can't self update. To manually perform an update, follow the steps:

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: 

1. Choose Apple menu
2. Then System Settings
3. Next click Network in the sidebar,
4. Select a network service on the right,
5. Click Details
6. 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 installer isn't working on Windows

Currently, you need Internet Explorer 11 installed on your Windows PC to run the Jagex Launcher Installer, otherwise you will see this message:

Even if you don't use Internet Explorer as your main browser, you will still need Explore 11 installed for the Launcher to work correctly.

 

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.
