Regardless of how difficult it is to correctly type, it is nonetheless causing plenty of irritation for gamers who just want to enjoy the game. Happily, though, you no longer need to worry. Just sit back, relax, and read this article. We've included everything you need to know about this error - what it is, and how to fix it. We haven't told you how to pronounce it though.

How To Fix Warzone BLZBNTBNA00000012 Error

If you receive a Warzone BLZBNTBNA00000012 Error message, then the first method to try to fix it is as follows:

Start by checking for game updates by completing the following steps:

  • Open the Battle.net desktop app.
  • Click the icon of the game you are trying to repair.
  • Click the cogwheel next to the Play button and select Check for Updates.

But in the meantime, here are our top suggestions for resolving the problem, temporarily at least:

  • Aside from checking for the latest updates, your first step is to try running the Battle.net repair tool. To do this:
    • Click the cogwheel next to the Play button and select Scan and Repair.
    • Click Begin Scan.
    • Wait for the repair to finish.
  • This might resolve the problem. But if not, then check to see where your game is installed. If it's in DownloadsDesktopWindows, or Temp folders, then try reinstalling it in another folder.
  • Make sure the game has not been granted adminstrator privileges. While for many games, granting adminsitrator privileges fixes problems, in this instance, it might actually trigger the issue. To check this, right-click on the game's excutable file, and look for Run as administrator. Ensure that the box next to this is not ticked.

Further Potential Fixes

  • Go to Warzone in the Battle.net Launcher.
  • Select the gear icon in the Play button and select Options.
  • Select Game Settings.
  • Uncheck the box next to 'Additional command line arguments' and delete any text in the field below it.
  • Select Done.
  • Relaunch the game.

If that method is unsuccessful, then one other suggested fix to try is this:

  • Go to the folder where the game is installed.
  • Create a new folder and move the entire game folder 'Call of Duty Modern Warfare' there.
  • Now, reboot the Battle.net client and Warzone will show as 'Install' instead of 'Play'. Do not install the game. Simple click on the text below Install that says ‘Locate the game’.
  • Next, browse and find the warzone folder that you put inside the new folder.
  • The Battle.Net client will initialize and the game should work.

If this is also unsuccessful, then the usual troubleshooting rules apply - try rebooting your computer, relaunching the game, and checking for updates. You may want to consider contacting Activision for further support. Either via Twitter, or via their official support website.
