How to Fix Epic Games Error Code Ii-E1003

Now let’s explore the possible solutions to fix the error code Ii-E1003 in the Epic Games Launcher.

1. Verify Game Files

The easiest and quickest solution recommended by the Epic Games technical team is to verify the game files. Here’s how you can do it:

  • Go to your library.
  • Select the game name.
  • Click on the three dots and choose “Verify.”

2. Check the Internet Connection

Make sure that your internet connection is stable and working properly. Since this error occurs during the download of game files, an unstable or weak internet connection could be the cause. If you’re using Wi-Fi, try connecting via Ethernet to see if that resolves the issue. Additionally, if you’re experiencing connectivity problems with your Wi-Fi, consider resetting your router by turning it off, unplugging it from the power source and other devices, waiting for a few minutes, and then plugging it back in. Wait for the signal to return before trying to connect to the internet again.

3. Disable the Firewall

Your firewall may sometimes block requests from certain programs if it sees them as potentially harmful. If you’re encountering the error code Ii-E1003 in your Epic Games Launcher, the firewall might be causing the problem. To address this issue, temporarily disable your system’s firewall by following these steps:

  • Go to the Control Panel from the Windows search bar.
  • Open “Systems and Security.”
  • Select “Windows Defender Firewall.”
  • Turn on the Windows Defender Firewall option.
  • Click on the “Turn off Windows Defender Firewall (not recommended)” button under both the Private network settings and Public network settings.
  • Click on “OK” and close the window.

4. Disable Antivirus

Antivirus programs can sometimes interfere with the operation of certain programs on your device. If your antivirus software considers Epic Games to be malware, it may prevent the launcher from functioning properly. To prevent this, consider temporarily disabling your antivirus program while opening and downloading games from the Epic Games Launcher. Each antivirus program has a different process for disabling it, so make sure to check the instructions specific to the antivirus software you’re using.

5. Uninstall and Reinstall the Epic Games Launcher

If none of the above solutions work, you can try uninstalling the Epic Games Launcher and then reinstalling it later. Follow these steps to uninstall the launcher:

  • Go to the Control Panel.
  • Click on “Programs.”
  • Select “Uninstall a Program.”
  • Find “Epic Games” in the list of programs.
  • Right-click on “Epic Games” and select “Uninstall.”

After uninstalling the launcher, visit the official Epic Games website to download and reinstall the launcher.
