'PVP.net Patcher Kernel has stopped working' Error

The 'PVP.net Patcher Kernel has stopped working' error is associated with the League of Legends (LoL) video game. LoL is one of the biggest games in the world, with millions upon millions of active players. As such, encountering the 'PVP.net Patcher Kernel has stopped working' error that will prevent LoL from even launching, could be a major source of frustration. Luckily, there are a couple of potential solutions that will not require you to reinstall LoL. 

Run LoL with administrator privileges

The 'PVP.net Patcher Kernel has stopped working' error is usually caused due to insufficient permissions to run the program. As such, the first thing that users should try is to run LoL as an administrator. 

1. Log in to an administrator account.
2. Locate the LoL shortcut on the desktop or the game's executable, and right-click it.
3. From the contextual menu, select the 'Run as administrator' option. 
4. Try to launch LoL and see if the error has been fixed. 

To always open LoL with admin permissions, right-click the executable (or the shortcut) and go to 'Properties.' Once there, select the 'Compatibility' tab and check the 'Run this program as administrator' checkbox. Click the 'Apply' button to save the changes.

End all LoL processes

One potential fix for the 'PVP.net Patcher Kernel has stopped working' error is to end all processes related to LoL and then attempt to start the game again. To make sure that there are no active LoL processes, you can use the Task Manager tool. Press Ctrl+Shift+Esc keys on the keyboard to open the Task Manager window. You will be presented with a list of all active processes that are currently running on the system. Find the ones associated with LoL, right-click them, and select 'End task.' Now, make sure that you are running LoL as an admin and then try to start the game. 

Delete the game patch files

Corrupted or incorrectly configured game patch files also could lead to the 'PVP.net Patcher Kernel has stopped working' error. LoL will then download and replace the missing files automatically, hopefully fixing the problem. 

1. Locate the RADS folder. It is usually inside the League of Legends folder. 
2. Open 'projects.'
3. Go to 'lol_air_client.'
4. Open 'releases.'
5. Find the latest created folder as well as the 'releasemanifest' and 'S_OK' files. Delete them. 
6. Open the 'deploy' folder.
7. Find, select, and delete the following files - 'properties,' 'META-INF,' 'logs,' and 'LoLClient.exe.'
8. Restart your computer and launch LoL as an administrator.
