How do i fix LoL DirectX errors on PC?

  1. Delete the Game.cfg File
  2. Update your graphics card driver
  3. Delete the League of Legends subfiles
  4. Repair the NET Framework

1. Delete the Game.cfg File

  1. Open File Explorer.
  2. Go to the following path: C:/Riot Games/League of Legends/Config
  3. Alternatively, right-click your League of Legends shortcut and select Open file location.
  4. After, right-click the game.cfg file in the Config subfolder.
  5. Then, click Delete.

Some League of Legends players have fixed the DirectX error by deleting the game.cfg file. That’s a straightforward resolution which is worth a shot.


2. Update your graphics card driver

  1. Press the Windows key + R.
  2. Enter appwiz.cpl in Run’s open text box.
  3. Select your display driver listed in Programs and Features.

  4. Press the Uninstall button then elect the Yes.
    • To manually update the graphics card driver, you’ll need Windows platform and video card model details at hand.
  5. You can check those details by entering dxdiag in Run and clicking OK.
  6. Note down the graphics card model and manufacturer details included on the Display tab.
  7. Next, open the graphics card manufacturer’s website (usually NVIDIA, AMD or Intel) in a browser.
  8. Select your graphics card model and Windows platform on the driver search drop-down menus.
  9. Download the latest driver.
  10. Install it and restart your computer.

The LoL error message suggests that you make sure your video card is using the latest video drivers from the manufacturer. So, that’s a pretty big clue for a potential fix!

Update your drivers automatically

If you don’t want to spend the time and search for the GPU drivers yourself, you can use a dedicated third-party tool that does that for you.

As such, you should download DriverFix, a great app that updates all of your hardware and software drivers. The program will search your PC components and apps for compatible drivers, and installs them for you.


3. Delete the League of Legends subfiles

  1. First, open the game’s Config folder by entering the following in File Explorer’s folder path bar: C:Riot/Games/League of Legends/Config
  2. Select the game.cfg and input files in the Config subfolder, and delete them.
  3. Then open the RADS subfolder within the League of Legends subfolder.
  4. Select the lol_game_client and lol_game_client_en_us subfolders, and then delete them.
  5. Open the League of Legends launch window, and click the ? button to open a Help window that includes four options.
  6. Press the Repair button on the Help window to fix corrupt files.

Some LoL players have fixed the DirectX error by deleting a few subfiles and subfolders and then running a repair with the game’s Repair option.


4. Repair the NET Framework

  1. Download the NET Framework Repair Tool.
  2. Open the NET Framework Repair Tool and press Next.
  3. Alternatively, you can also  uninstall your NET Framework and reinstall it.
  4. Go to Control Panel.
  5. Select Uninstall a program.
  6. Find Net Framework, right-click on it then uninstall.
  7. Download the program.
  8. Run the installer and wait for it to finish.

As Microsoft NET Framework is an essential prerequisite for DirectX, you might need to repair your NET Framework setup.
