Try these fixes one by one and see if they solve your problem.

Fix 1: Run the program as an administrator

This is the simplest and easiest method to go around the pvp.net patcher has stopped error, and you should try it before embarking on another solution.

Executing the program as an administrator means notifying the system that the program is safe and that you need administrator privileges. Most standard user accounts run in normal mode, which means the user has restricted access from performing executions that affect the operating system.

This is usually for the good of the user and the operating system itself, as it prevents accidental deletions and unintended problems. Running as an administrator removes the privileges, and any operation you run will not perform without any hindrance from firewalls and system checks.

Step #1

On the application, right-click and select “Run as administrator.”

If the error goes away after running as an admin, you can change the client properties always to have administrator rights or log into the system using an administrator account. Proceed as below.

Step #2

Navigate back to the application and right-click it again. Choose “Properties.”

Step #3

Navigate to the “Compatibility” tab.

Step #4

Check the “Run this program” as an administrator option present close to the bottom of the window.

Step #5

Select “Apply” to save changes and then exit.

Check if you are still experiencing the pvp.net patcher kernel has stopped error.

Fix 2: Ending the Program in Task Manager

This is another workaround to fix the pvp.net patcher kernel has stopped working error is to force stop it. This method has worked for many users.

Ending the program with the Task Manager closes it completely, kills background processes associated with it, and frees the memory used to store the application data.

Step #1

After closing the program, start it again by running it as an administrator.

Step #2

Open the “Task Manager” by pressing Windows + R and typing “taskmgr” on the dialog box or clicking on the taskbar and selecting “Task Manager.”

Step #3

Once inside, navigate to the “Processes” tab and click it.

Step #4

Locate all the processes related to your program, for example, League of Legends Client (LoLClient.exe), Riot Client Patcher (LoLLauncher.exe), and LolPatcher.exe

Step #5

End all of these processes by right-clicking them and selecting End task. Sometimes your PC may also be running too many CPU resources, so clearing them out may help.

Step #6

Re-open League of Legends by running in administrator mode.

Fix 3: Removing Patch Files

The application refuses to work because the program patch files are corrupted or there was a problem with their configuration. Remove game patch files to fix the pvp.net patcher kernel has stopped working error.

The application will automatically download any missing patch files after you remove them.

Step #1

Open “Explorer” and open the file location where the League of Legends is installed on your computer.

Step #2

Open the “RADS” folder.

Step #3

Once there, open the “projects folder,” then the “lol_air_client” folder, and finally, the latest folder inside “releases.”

Step #4

Within that “releases” folder, look for the latest folder and open it.

Step #5

Delete the files “S_OK” and “releasemanifest.”

Step #6

Now open the Deploy folder and delete the following files:

• “Properties”
• “META-INF“
• “logs“
• “LoLClient.exe“
