Start by making sure your internet connection is up. Also, go to Runescape’s Downdetector page and see if there’s any reported outage in your area.

3. Select the Repair option and click Next.
4. Wait for the process to complete and relaunch the app.

2. Clear app cache

1. Type Windows key + R, enter %localappdata% and press Enter.
2. Look for a folder related to Jagex or RuneScape, such as Jagex or JagexLauncher.
3. Look for any files or folders that contain cache or temporary data (often named cache, tmp, or similar).
4. Right-click on it and select Delete.

3. Run Jagex in compatibility mode

1. Right-click the Jagex Launcher shortcut and select Properties.
2. Go to the Compatibility tab and check Run this program in compatibility mode for: Windows 7.
3. Click Apply, then OK, and restart the launcher.

This method should help if the issue started happening after you ran Windows updates or upgraded to a newer OS.

Running in compatibility mode ensures the game uses stable settings from an older version of Windows.

4. Allow Jagex through the Windows Firewall

1. In the search bar, type Windows Defender Firewall and open it.
2. Click Allow an app or feature through Windows Defender Firewall.
3. Scroll to find JagexLauncher.exe.
