Error 3 may be caused by incorrectly entering your login information. It can also occur if you are unable to accept the End User License Agreement and Terms of Use updates that accompany each patch. Follow these steps to resolve the issue.

  1. If you receive an Error 3 in-game, your digital purchase is still under Starter Account restrictions. If 72 hours have passed since your purchase, change your Battle.net password to force the account database to refresh.
  2. Make sure you have the latest version of the Battle.net Desktop App installed.
  3. Delete the Battle.net Cache Folder to remove any corrupted data.
  4. Add contact information to your Battle.net account.
  5. If you have a mobile Battle.net Authenticator, resync it.
  6. Try to log in to the game from a different computer.
  7. Log in to a different play region. For example, if you normally play in The Americas, log in to Europe or Asia. This method will often push a new copy of the EULA and TOU to your computer. Details on how to change your server region are in the Global Play article.
  8. Create a new Administrator account on your computer, then launch the game from it.
