Set Epic Games to Run as an Administrator

  3. To save the settings selected, click Apply > OK.

Disable Administrator Right for Affected Games

Epic’s support service advises users to disable administrator privileges for affected games to fix error LS-0013. Furthermore, players who’ve needed to fix this gaming issue have also confirmed that works. This is how you can deselect the Run this program as administrator option for Fortnite.

  1. Bring up File Explorer by using the Windows logo + E hotkey to activate that folder navigation tool.
  2. Navigate to the Fortnite installation folder, for which the default path is C:\Program Files\Epic Games\Fortnite\.
  3. Open the FortniteGame\Binaries\Win64 subfolder from Fortnite’s folder.
  4. Right-click the FortniteClient-Win64-Shipping.exe file to select Properties and Compatibility.
  5. Unselect Run this program as an administrator if that setting is selected.

    The Compatibility tab

  6. Select Apply to save the changes and OK to exit.
  7. Repeat the previous three steps for the FortniteLauncher.exe, FortniteClient-Win64-Shipping_EAC.exe, and FortniteClient-Win64-Shipping_BE.exe files.

You can apply this potential fix for different games much the same. Look for a game’s EXE (application) files within its installation directory. Then, unselect the Run this program as administrator option for the game’s EXE files.

Apply a Clean Boot

Don’t rule out the possibility of conflicting background apps causing error LS-0013 on your PC. You can address this potential cause by disabling third-party startup items, which is a troubleshooting method called clean booting. This Microsoft page tells you how users can apply the clean boot troubleshooting method.

Temporarily Disable Firewalls

Epic also advises users to temporarily disable firewalls for troubleshooting error LS-0013. Windows Defender Firewall can block multiplayer games like Fortnite from starting when not allowed through it. Try turning off that firewall before playing Fortnite or alternative games like this.

  1. First, open the Run command dialog.
  2. Enter ncpa.cpl inside Run and click OK.
  3. Click Turn Windows Defender Firewall on or off along the left side of the Control Panel applet.
  4. Select the two radio buttons with the Turn off Windows Defender Firewall labels.

  5. Click OK to exit Customize Settings.
  6. Try starting Fortnite or an alternative Windows game.

If this potential fix works, you should still turn Windows Defender Firewall back on after playing. Or you can add the game EXE file to that firewall’s allowed list with the Public and Private checkboxes selected for it. You can do that by going through the steps on this Microsoft help page.

Those potential solutions will usually fix the Launched Failed LS-0013 error for Fortnite and other Windows PC games. If that gaming issue persists, consider contacting the Epic help service. This Epic help page provides instructions for contacting that support service.
