True fans of the League of Legends game surely know about this error. You’re enjoying the game and all of a sudden error message, “pvp.net patcher kernel has stopped working“!
The error pops up, and League of Legends crashes. Irritating, to say the least. Furthermore, the client program refuses to open again, and even reinstalling sometimes doesn’t work.
This error is different from the other kernel security check failure error.
The error occurs quite randomly, and there are no special conditions per se that cause it. Many times, it happens when the game patch files are corrupt or when you run the program as a standard user instead of as an administrator. There are several ways therefore to fix the pvp.net patcher kernel error. For example, you can try removing game patch files, to begin with.
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 that you’re notifying the system that the program is safe, and you need administrator privileges. Most standard user accounts run in normal mode, which means that 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 is taking back the privileges, and any operation you run will not perform without any hindrance from firewalls and system checks.
On the application, right-click and select “Run as administrator“.
If the error goes away after running as an admin, then you can change the client properties to always have administrator rights or log into the system using an administrator account. Proceed as below;
Navigate back to the application and right-click it again. Choose “Properties“.
Navigate to the “Compatibility” tab
Check the “Run this program” as an administrator option present close to the bottom of the window.
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 the program, and frees the memory that had been used to store the application data.
After closing the program, start it again by running it as an administrator.
Open the “Task Manager” by pressing Windows + R and typing “Taskmgr” on the dialog box, or clicking on the taskbar and select “Task Manager“.
Once inside, navigate to the “Processes” tab and click it.
Locate all the processes related to your program, for example, League of Legends Client (LoLClient.exe), Riot Client Patcher (LoLLauncher.exe), and LolPatcher.exe
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.
Re-open League of Legends by running as 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.
Open “Explorer” and open file location where the League of Legends is installed on your computer.
Open “RADS” folder.
Once there, open “projects folder“, then the “lol_air_client” folder, and finally the latest folder inside “releases“.
Within that “releases” folder, look for the latest folder inside and open it.
Delete the files “S_OK” and “releasemanifest“.
Now open the Deploy folder and delete the following files:
Restart your computer and then run the program as an administrator. Try to run LOL and see if you are still experiencing the pvp.net patcher kernel has stopped working error.
