League of Legends (LoL) may show a "LoL Repairing" error when you try to launch it. As with any error, the cause is usually a problem in the game files, outdated drivers or issues with your internet connection. In this article we cover the fix for the LoL Repairing error if you are affected by it.

How Do You Fix the LoL Repairing Error? 2025

What Is the LoL "Repairing" Error?

The "Repairing" error in LoL is a problem that appears when the game client (launcher) is started or when an update is being attempted. The client usually gives this error when it runs into an error, cannot complete updates or detects missing files. The "Repairing" message shows that the system is trying to repair the game's files automatically. However, this process can fail in some cases, which blocks players' access to the game.

This error can come from different causes, ranging from missing or corrupted game files to internet connection problems. Now let's go through the steps you can use to fix this error in detail.

Try Restarting the Client

As a first step, close the LoL client completely and restart it. Sometimes the "Repairing" error can appear because of a temporary problem in the client. Waiting a few minutes after closing the client and starting it again can help solve the problem.

Restart Your Computer

In some cases, other programs or processes running on your computer can prevent the LoL client from working properly. Restarting your computer clears unnecessary data from memory and can help the game client run more smoothly.

Run the Client as Administrator

Running the game as administrator can be an effective fix, because the LoL client needs permission to access certain files and settings, and the "Repairing" error can appear without it.

• Steps:

• • Right-click the LoL client shortcut.
  • Click the "Run as administrator" option.

This lets the game access the files it needs and can eliminate access problems during the update or repair process.

Check Your Internet Connection

A stable internet connection is needed to update the game files. If your connection is slow or intermittent, the client cannot complete updates and can cause the "Repairing" error. By checking your internet connection, you can tell whether the problem lies there.

• Steps:

• • Restart your modem.
  • Test your internet speed.
  • If possible, use a wired connection for a more stable link.

Start the LoL File Repair Process

The repair feature in the LoL client is very effective at fixing corrupted or missing game files. If the repair process the client starts on its own fails, you can try starting it manually.

• Steps:

• • Open the LoL client.
  • Click the gear icon in the top right corner.
  • Click the “Initiate Full Repair” option and wait for the process to finish.

This process may take some time, but it can fix missing or corrupted parts of the game files and help resolve the "Repairing" error.

Reinstall the Game

If the steps above did not solve the problem, there may be a deeper issue with the game files. In this case, the most effective fix is to uninstall the game completely and reinstall it. This clears out all corrupted files and lets the game be installed again in full.

• Steps:

• • Go to your computer's Control Panel and uninstall LoL.
  • Download the latest version from Riot Games' official website.
  • Reinstall the game and wait for the updates to finish.

Check Your Firewall and Antivirus Settings

Some antivirus programs and firewalls can block the game files or the client and cause the "Repairing" error. These programs may detect the game files as a potential threat and stop the client from updating.

• Steps:

• • Check your firewall and antivirus settings.
  • Mark the LoL client as a safe program, or temporarily disable your security programs.

After disabling your antivirus, try the game's updates again; if the problem is solved, you can revisit your security programs.

Change Your DNS Settings

Sometimes DNS settings can cause problems reaching Riot Games servers. Switching to a public DNS server such as Google DNS can fix connection problems.

• Steps:

• • Open “Network and Sharing Center” from the Control Panel.
  • Select the connection you are using and click "Properties".
  • Open the “Internet Protocol Version 4 (TCP/IPv4)” option.
  • Manually enter the DNS server addresses "8.8.8.8" and "8.8.4.4".
