Common Problems

You need a decryption key to install {game_name}. Either our server is too busy to give you one, or {game_name} hasn't been released yet.
Error Code: BLZBNTAGT000002C1

This error means that the Blizzard Update Agent couldn't obtain a decryption key from Blizzard services for installation. Follow the steps below to resolve the issue:

  1. If the game you are trying to install has not been released, wait until the game is released and try again.
  2. If the game was recently released, please wait a few minutes and try again. Our servers may be busy or overloaded.
  3. If you're using a game disc to install the game, make sure you're connected to the internet.
  4. Make sure your system clock time and time zone are accurate and try again.
  5. If you continue experiencing issues, visit the Blizzard Downloads page and obtain a new copy of the game installer.
