  1. Locate the directory where League of Legends is installed.
  2. Open the RADS folder.

    • META-INF
    • properties
  7. Restart your PC.
  8. Relaunch the game and see if the error has been fixed.

Solution #4: Uninstall and reinstall the game

Uninstalling and reinstalling the game using the most recent setup file has resolved a number of technical issues. New setup file versions are updated every now and then, so the previously reported issues like the “Pvp.net Patcher Kernel Has Stopped Working” may have already been addressed in the new setup file version.

Below is a guide of the basic steps to uninstall League of Legends on Windows:

  1. Go to the Start menu.
  2. Select Control Panel.
  3. Navigate to Programs and Features.
  4. Click League of Legends.
  5. Hit the Uninstall button.

After uninstalling the game, proceed with reinstalling it. Here’s how:

  1. Download the recent version of the game’s setup files from the official website.
  2. Once the download is complete, run the setup file. This should be located in the League of Legends folder on your desktop.
  3. When the setup files are downloaded, the installation processes will automatically start. If prompted, install the game in your C drive.
  4. Once the installation is complete, the game’s patcher will launch automatically. If you wish to open the game manually, simply double-click on its shortcut file or run the LeagueClient.exe file in the folder where you installed the game.

Solution #5: Check the game’s server

Sometimes, the error message appears because the game’s servers are overloaded with requests. As a result, users cannot successfully launch the game and the error message appears. And since this is a server-related issue, the best fix is to keep trying to sign in. You may also check the social media accounts of the game to know the current status of its servers.

Solution #6: Install any pending Windows update

This fix is applicable to new Windows users who still haven’t updated their operating systems. By installing all pending Windows updates before launching the game, the error message can be eliminated.

To ensure your Windows device is updated, follow these steps:

  1. Go to the Start menu and select Settings.
  2. Select Update and Security.
  3. Navigate to the Windows Update section and click the Windows Update button.
  4. Finally, hit the Check for Updates button. If an update is available for your device, it will automatically appear on the new window that appears.
  5. Install it by clicking the Download and Install Now button.
  6. Once Windows is up to date, restart the game.

Solution #7: Disable your antivirus temporarily

Antivirus programs are notorious for detecting false positives within the game’s update and installation files. As a result, the game’s patcher may not always launch successfully. The main reason these files are flagged as threats is that they are often installed on a device in a .ZIP format, which makes them quite difficult to open and scan.

By disabling your antivirus temporarily, you can resolve any errors you encounter while trying to launch the game. To temporarily disable your real-time protection with Windows Defender, follow the instructions below:

  1. Go to the Start menu and select Settings.
  2. Navigate to Update and Security and click Windows Security.
  3. Click Virus and Threat Protection and choose Manage Settings.
  4. Now, toggle off the switch next to the Real-Time Protection option.
  5. By this time, Windows Defender should be temporarily disabled. Should you wish to enable it again, just follow the steps above. But this time, toggle on the switch next to Real-Time Protection. Also, it is worth noting that if you have scheduled scans, they will still continue to run. But the files you have just downloaded or installed will not be scanned until the next scheduled scan.
  6. Once your antivirus has been disabled, try launching the game and see if the error message still shows.
