RuneScape is a popular multiplayer online game. Many players love this game for its free spins and web browser accessibility. However, some RuneScape users claim that every time they try to open Game Launcher, the message “RuneScape client encountered an error” appears on their computer screens.

The error has been reported in Windows 7, Windows 8.1 and Windows 10. There are many potential issues that can lead to this error. If you are struggling with the same problem, don’t worry. In this article, you will learn how to troubleshoot and fix errors on your Windows computer one by one.

Clear cache

Clearing cache files often fixes most random crashes. It also fixes some audio issues not caused by file uploads. To do this, follow the instructions in the Support section of the RuneScape website: Clear cache and install cache on a second hard drive.

Update your Windows

Updating Windows will fix any previous errors on your computer. A Windows update will also fix the AMD GPU drivers. AMU GPUs are not supported by their proprietary utility (Adrenalin). Drivers are updated using Windows Update components. So, follow these steps and update Windows.

  • Press Windows Key + R.
  • Type “ms-settings: windowsupdate” and press Enter or click OK.
  • In the right pane, select the “Check for Updates” option.
  • Then follow the instructions on the screen to complete the update process.
  • After updating Windows, restart your computer and look for the error.

Increased maximum heap usage

You can increase the maximum number of heaps used by the RuneScape client. This is often the recommended troubleshooting step on the official forum. Do it:

  • Open% USERPROFILE% \ jagexcache \ jagexlauncher \ runescape \ runescape.prm in an editor.
  • Replace each instance of -Xmx384m with a higher value. -Xmx512m recommended
  • Save and close the file
  • Allocating too much heap memory can cause the game to become unstable. If your client crashes after increasing the maximum heap size on the desktop, reduce the maximum heap size and try again. -Xmx512m is generally considered a safe heap size and should not be increased unless absolutely necessary.
