Fix PVP.Net Patcher Kernel Stopped Working Error
You’re all set to launch League of Legends, feeling the hype… and BAM 💥—”PVP.Net Patcher Kernel has stopped working.” Ouch. That one error can ruin your gaming mood instantly.
But don’t worry. Fixing this bug is easier than you think. You don’t even need to be a computer genius. Let’s walk through the simple steps to get you back in action quickly.
🔍 What is this error anyway?
When you see this message, it usually means your game client can’t start correctly. The cause? Something getting in the way—permissions, corrupted files, or outdated software.
So let’s smash this bug with a few easy fixes.
🛠️ Fix #1: Run as Administrator
This one is simple and works most of the time.
- Right-click the League of Legends shortcut.
- Click Run as administrator.
Why does this help? Your computer protects certain system features, and the game might need a permission boost to start right.
Still getting the error? No problem, let’s try the next one.
🔄 Fix #2: Kill the Process and Restart
Sometimes the game is running in the background, stuck in limbo.
- Press Ctrl + Shift + Esc to open Task Manager.
- Find LeagueClient.exe or PVP.net Patcher in the list.
- Right-click it and hit End Task.
- Now reopen the launcher.

🧹 Fix #3: Clear the LOL Patch Folder
If a patch file is corrupted or broken, the client won’t run.
- Go to your LOL install directory (usually C:\Riot Games\League of Legends\).
- Open the RADS folder, then the projects folder.
- Delete the folder named lol_launcher and lol_patcher.
Don’t worry. The game will redownload these the next time you launch it. Fresh files = happy patcher. 😊
🔁 Fix #4: Repair the Game Client
Still no luck? Time to let the client fix itself.
- Open the League of Legends launcher.
- Click the gear icon ⚙️ in the top right.
- Click Repair.
This process takes a few minutes, but it checks and replaces anything broken.
💻 Fix #5: Compatibility Mode Magic
This game was made a long time ago, and sometimes it wants you to pretend your PC is from 2010. 😆
- Right-click the League of Legends shortcut.
- Go to Properties.
- Under the Compatibility tab, check Run this program in compatibility mode for:
- Select Windows 7.
- Click Apply, then OK.


🛡️ Fix #6: Disable Your Antivirus Temporarily
Sometimes your antivirus tries to protect you *a little too much.*
It might block the game launcher by mistake. Try turning it off for a moment and launching the game.
☠️ Warning: Don’t browse weird websites while it’s off! And turn it back on after testing.
✨ Bonus Tip: Reinstall as Last Resort
If all else fails, it may just be time for a clean reinstall.
- Uninstall League of Legends completely.
- Restart your computer.
- Download the latest version from the official website.
- Reinstall and relaunch.
This might seem like a pain, but it can fix the trickiest problems.
