What Is “Pvp.Net Patcher Kernel Has Stopped Working” Error in Windows 10?

The ‘PvP.net Patcher Kernel has stopped working’ error is known to affect the League of Legends video game. The error appears randomly when a player tries to launch the game or run the Riot Client. Sometimes, the game might even stop suddenly when you’re in the middle of a battle and the client program refuses to run again.

In most cases, the ‘PvP.net Patcher Kernel has stopped working’ error pops up when you run LOL without administrator rights or if the game files have been corrupted. Such an error can be quite irritating, especially considering how addictive the game can be, and you’d want it fixed as soon as possible. Hopefully, there are several ways to resolve the issue once and for all.

How to Fix League of Legends “Pvp.Net Patcher Kernel Has Stopped Working” Problem

Fix 1: Run the Game as an Administrator

One of the easiest and most effective ways to get League of Legends up and running is to give it full administrator rights. Most players discovered that running LOL as an admin resolved the “PvP.net Patcher Kernel has stopped working” issue. The thing is, when you give a program administrative access, it operates without any restrictions from the system, such as firewalls. If this fix works, you can configure the game’s properties to always run with admin access. To run the game with admin rights, follow this simple guide:

  1. Right-click the game’s icon on your desktop and select “Run as administrator”.
  2. Relaunch League of Legends and if it runs without triggering the “PvP.net Patcher Kernel has stopped working” error, then proceed with the next steps below to permanently run the game with elevated rights.
  3. Right-click LOL’s icon again and select “Properties”.
  4. Switch to the “Compatibility” tab and check the “Run this program as an administrator” option.
  5. Click Apply > OK to save the changes.

You should now be able to battle it out with other players without the game suddenly stopping midway.

Fix 2: Run LOL in Compatibility Mode

If League of Legends failed to function even after giving it administrative access, then you can try running the game in compatibility mode. Sometimes, newer operating systems like Windows 10 might not be compatible with some games. To proceed, follow these steps:

  1. Right-click the game’s icon on your desktop and open its “Properties”.
  2. Go to the “Compatibility” tab, and click on the “Run this program in compatibility mode for:” option.
  3. Choose “Windows 7” from the drop-down list.
  4. Click Apply > OK.

If the game refuses to run properly with “Windows 7” as your selected OS, try Windows 8 or Windows 10.

Fix 3: Restart the Game

Sometimes, a program may get stuck due to several reasons. Ending the program in ‘Task Manager’ closes all of its processes and helps to get the program back to its functioning state. For this reason, restarting League of Legends can also resolve the “PvP.net Patcher Kernel has stopped working” problem on your Windows 10 PC.

Here’s how:

  1. Open “Task Manager” using the Ctrl + Shift + Esc keyboard shortcut or simply right-click your taskbar and select “Task Manager”.
  2. Next, find all the processes related to League of Legends under the “Processes” tab, select them one by one, and click “End task”.
  3. Once you’ve stopped all the processes related to the Riot Client, exit “Task Manager” and relaunch League of Legends as an admin to check whether the issue has been resolved.

Fix 4: Delete Game Patch Files

If the game patch files have been corrupted, then deleting them can get rid of the “PvP.net Patcher Kernel has stopped working” error. Once you delete all the files, the program will automatically download all the files again.

Here are the steps to remove LOL’s patch files:

  1. Open “File Explorer” and browse to the directory containing the League of Legends files, which in most cases is the Local C drive. However, it depends on which drive you have the game installed.
  2. Once you find the directory, open the “RADS” folder and go to this path: projects > lol_air_client > releases> “Select the latest folder present”.
  3. Find and delete the “S_OK” and “releasemanifest” files.
  4. Next, locate the “Deploy” folder and delete the following files:
  • ‘logs’
  • ‘META-INF’
  • ‘lol.properties’
  • ‘LolClient.exe’
  1. Finally, restart your PC and launch League of Legends as an administrator.
