How to Fix Patcher Kernel has Stopped Working Issue

Here are some quick tips to fix Patcher Kernel has Stopped Working Issue.

Run as Administrator

One of the easiest ways to get around any of the packages not working the problem is to give full administrative access to it. So try to run the game as administrator. It is as simple as right-clicking on the file which says .exe in its extension and selecting the option that says Run as Administrator.

Close and Restart Related Services

Open task manager and close the programs related to the game from the background. Click on the entries that are related to the game and click end task. Then, restart the game as usual and see if that fixes the issue.

Make sure that you close out all the related programs that might be running in memory. Things such as LoLClient.exe which is the League of Legends client, LoLLauncher.exe which happens to be the Riot Client patcher, and also close the LoLPatcher.exe.

If it does not work, restart your computer system and do the same things once again. A quick reboot fixes even the most severe looking problems like “ patcher kernel has stopped working” sometimes. Why not give it a shot?

Remove Patch Files

Often, there are some files in any game added for improved convenience. The game will function just fine even without those files and patches. You can try to remove some minor patches and other small program files from the game’s installation folder and rerun it.

Sometimes, the game will be better off with those troublesome and unnecessary patch files deleted. Open the native file manager on your PC. Go to the location where the game has been installed.

Usually on the local C drive, but it depends on which virtual drive you have installed it. Once you are there, open the main folder, and you will see a folder which is named as RADS. Inside that folder, go to projects->lol_air_client->releases->latest folder.

In the latest folder, you will have two patch files, releasemanifest, and S_OK. It is safe to delete them both, so do it. Along with these two, you will also see a folder named deploy. Open it.

In it, you can get rid of the folder logs, META-INF and files and LoLClient.exe. Now restart the game. What the game will now do is that, since we have cleared out these potentially damaged files and patches, it will re-create them in their respective places. Note that the game may take a little bit longer to load this time, but will not throw you that annoying Patcher Kernel Has Stopped Working error message.

Try the Compatibility Mode

Sometimes games might cause weird issues with newer version of operating systems. So it is a smart choice to try and run them in compatibility mode, should you encounter any errors. To do that, create a shortcut of the game on your desktop first. I imagine that you already have one like everyone else, to make it easier to launch the game.

So right click on the desktop shortcut of the game and click on properties. Then, once the new window pops up, click on compatibility button that you see. In the options listed, “run this program in compatibility mode for” and select the windows version that you are using.

Pretty much all of them will be listed. Once you have set your Windows version, click on the option on the bottom that says run as administrator. Then hit apply and OK.

You may reboot the system if you like, just to be sure. Now open the game as usual and see if still shows that error prompt. If it doesn’t, then great! Problem solved. If it did not work, there is only one option I’m afraid. That is option number 5.

Reinstall the Program

Yeah, this just might be the last option you have left, if you find yourself at this method after trying all the above but failed. Your game has some big-time installation issue or maybe something else.

It is better to remove it and reinstall it. Your current progress will apparently be lost, but that is the price you will have to pay because of your incompatibly troublesome system.

So far, Windows 8 people seem to be the most common ones among those who are affected by this Patcher Kernel Has Stopped Working error message. There are a couple of Windows 10 users too, but some of them have it running fine.


I guess it depends on a lot of sensitive things about your running OS. But all problems can be solved, and so can this, using the methods we have seen so far. Hope you won’t face “ patcher kernel has stopped working” from now. Good luck!
