How to Fix Diablo 3 Error Code 1

Diablo 3 error code 1 occurs due to corrupted game files, admin restrictions, or bad internet. To fix this error, we recommend that you try the following methods:

  • Repair corrupted game files
  • Run as administrator

1. Repair corrupted game files

As we already mentioned, error code 1 can occur due to corrupted or missing game files. Luckily, Blizzard’s launch client has a feature to restore game files. To use it:

  • Launch the Battle.net client.
  • Choose Diablo 3 from your game library.
  • Click on the gear icon next to the “Play”button.
  • Select “Scan and Repair”and click “Start Scan”.
  • Wait for the scan to complete and launch the game.

If the issue persists, continue to the next method.

2. Run as administrator

Another reason why this problem may occur is insufficient access to computer files. To fix this, you can run Diablo 3 as an administrator. This will provide the necessary access to the game and may resolve the issue. For this:

  • Click on the Windows search bar and type Diablo 3.
  • When the application starts, right-click on it and select “Run as administrator”.
  • You can also do this if you have a desktop shortcut.

3. Disable your antivirus or firewall.

Since Diablo 3 is an online game, an antivirus or firewall may interrupt gameplay. So before starting the game, you can try to disable the antivirus. To do this, click on the Hidden Icons panel. Then right-click on the antivirus application and select Disable.

If none of these fixes work, we recommend that you visit Blizzard’s official support forums or their Contact Us page.
