Blzbntbna00000012 ошибка варзон

The Blzbntbna00000012 error is one of the most diverse errors of Warzone (especially, Warzone Pacific), but it is mainly reported after a Battle.net client or Warzone update.

You may encounter the Blzbntbna00000012 error in Warzone due to many factors but the following can be regarded as the main ones:

Relaunch the Battle.net Client

A temporary glitch in the Battle.net modules (especially, the Update Agent) may cause the Blzbntbna00000012 error in Warzone. In this case, relaunching the Battle.net client after closing all the related processes in the Task Manager may solve the problem.

1. Exit the Warzone game and close the Battle.net launcher.
2. Now, right-click on Windows and select Task Manager.
3. Then, end all the processes related to Warzone and Battle.net (like UpdateAgent).
4. Now right-click on the Battle.net client and select Run as Administrator. If it asks to update, select No.
5. Then, again switch to Task Manager and end task related to Update Agent.
6. Now switch to Battle.net client and select Warzone.
7. Then click on Play and check if Warzone launches without throwing the Blzbntbna00000012 error.

Change the Region in the Battle.net Client

The Blzbntbna00000012 error could also be a result of a temporary glitch of the Blizzard regional server and changing the region in the Battle.net client may solve the problem.

1. Open the Battle.net app and near the right of the Play button, click on the globe icon.
2. Now select a different region (e.g., if using America, then select Europe), and afterward, click on the Play button to launch Warzone.
3. If it asks to update, let it update, and once launched, check if the game is clear of Blzbntbna00000012 error.

Delete the COD Folder in Documents

COD Modern Warfare’s folder in the user’s Documents directory holds the settings and configurations of Warzone. If the contents of the said folder are corrupt, then it may result in the Blzbntbna00000012 error. In this context, you can fix the error code BLZBNTBNA00000012 by deleting the COD Modern Warfare folder (the game will create a new folder with default settings upon launch) in the Documents directory of the system.

1. Firstly, make sure no process related to Battle.net and Warzone is running in the system’s Task Manager.
2. Then, right-click Windows and select Run.
3. Now navigate to the following:

   Documents

   

4. Then delete the COD Modern Warfare folder and launch Warzone to check if its Blzbntbna00000012 error is cleared.

Clear the Battle.net Cache

Warzone may show the Blzbntbna00000012 error if the cache of the Battle.net launcher is corrupt. Here, clearing the cache of Battle.net may solve the problem.

1. Firstly, make sure to end the Battle.net and Warzone processes in the system’s Task Manager.
2. Then, right-click Windows and select Run.
3. Now navigate to the following path:

   %programdata%

   

4. Then delete the folders related to Battle.net and Blizzard (like Blizzard Entertainment).
5. Now, navigate to the following paths (one by one) in the Run command and delete Battle.net or Blizzard-related folders:

   %appdata%
   
   %localappdata%

6. Then launch Warzone and check if the Blzbntbna00000012 issue is resolved.

If not, check if launching the Warzone game in safe mode solves the problem.

Remove Command Line Argument of Warzone in the Battle.net Client

Many users tend to set the Command Line Argument of Warzone in the Battle.net client to launch the game in DirectX 11 mode, but the incompatibility of the old DirectX version with the latest game modules may cause the Blzbntbna00000012 error. Here, removing the Command Line Argument of Warzone in the Battle.net client may solve the problem.

1. Open the Battle.net client and select Warzone.
2. Now open the game’s Options and choose Game Settings.
3. Then delete the argument in the Command Line Argument and uncheck the option of Command-Line Argument.
4. Now save the changes and launch Warzone to check if its Blzbntbna00000012 error is cleared.
5. If not, check if repairing the Warzone game in Battle.net solves the problem.

Manually Update the Battle.net Client without Uninstalling it

If the Battle.net client fails to update to the latest build (either due to a network issue or interference from the system’s security application), then manually updating the Battle.net client without uninstalling it may solve the problem.

1. Launch Battle.net client and select Warzone.
2. Now expand its Options and select Show in Explorer.
3. Then rename the Warzone/Modern Warfare folder and close the Battle.net app.
4. Now right-click Windows and select Task Manager.
5. Then make sure to end all the processes related to Warzone and Battle.net in the system’s Task Manager.
6. Now download the latest Battle.net client from the official website and once downloaded, right-click on the downloaded client.
7. Then select Run as Administrator and follow the prompts to update the client’s installation.
8. Now launch the Battle.net application and do not install Warzone.
9. Then open the Settings of Battle.net and select Downloads.
10. Now click on Change in Scan for Games and when asked to, point it to the folder renamed in step 3.
11. Then open Warzone through the Battle.net client and check if Warzone is cleared of the Blzbntbna00000012 error.
12. If not, check if updating the Battle.net client to the beta version solves the problem.

If the issue persists, check if modifying the Warzone install and only selecting Multiplayer solves the problem.

Rename or Relocate the Warzone Folder

There are some reserved names (Desktop, Windows, Downloads, PC, Temp, etc.) that should not be in the game’s installation path and if your game’s installation has any such name in its installation path, then it may result in the Blzbntbna00000012 error. In this case, renaming or relocating the Warzone folder may solve the problem.

Rename the Warzone Folder Path

1. Open the Battle.net client and select Warzone.
2. Now, open its Options and select Show in Explorer.
3. Now check the installation path of the game in the address bar and if it has any of the reserved names, then rename that directory.
4. Close the Battle.net client and make sure to end all of its related processes in the Task Manager.
5. Now launch to the Battle.net client and check if it is showing the Play button or Install button. If it is showing the Play button, click on it and check if the game is working fine.
6. If the Battle.net launcher shows the Install button for Warzone, then open the Settings of the Battle.net application.
7. Now open Downloads and click on Change in Scan for Games.
8. Then point it to the installation directory (with the renamed path) and afterward, launch Warzone to check if it is clear of the Blzbntbna00000012 error.

Relocate the Warzone Folder

If renaming the folder did not work, then relocating it may solve the problem.

1. Open the Warzone folder (as discussed above) and move it to another folder (preferably, in the root directory of the drive).
2. Now end all the processes related to Battle.net in the Task Manager and launch Battle.net. Do not worry if it shows the Install button (not Play) for Warzone.
3. Then, open the client’s Settings > Downloads > click Change in Scan for Games and point to the new path.
4. Now launch Warzone and check if it is operating normally.
5. If not, then check if putting the Warzone folder into Programs Files (x86) or in the Battle.net installation directory solves the problem.

Launch as Administrator from the Installation Directory

If the Battle.net client and Warzone game cannot access a protected system resource due to the non-availability of the administrator privileges, then it can cause the Warzone Blzbntbna00000012 error. In this scenario, launching Warzone and Battle.net applications as an administrator may solve the problem.

Launch the Battle.net Client as Administrator

1. Right-click on the Battle.net icon and select Run as Administrator.
2. Now select Warzone and click on Play.
3. Then check if the Warzone game is functioning normally.
4. If that did not work, check if launching bootloader.exe as an administrator in the installation directory of the Battle.net client solves the problem.
5. If not, check if launching bootstrapper.exe as an administrator in the Battle.net client’s installation directory clears the error.

Keep in mind that to make the process permanent, right-click on the file, head to its compatibility tab, checkmark Run This Program as Administrator.

Launch Warzone as Administrator

1. If the issue persists, make sure to end the Battle.net client and Warzone’s processes in the Task Manager.
2. Then, open the Battle.net client as administrator and select Warzone.
3. Now expand its Options and select Show in Explorer.
4. Then, right-click on Modern Warfare Launcher.exe and select Run as Administrator.
5. Now wait for a few seconds and then right-click on ModernWarfare.exe.
6. Then select Run as Administrator and once Warzone is launched, check if it is clear of the Blzbntbna00000012 error.
7. If not, log out of the Battle.net client, launch Warzone as administrator, ignore Battle.net and its sign-in page, then check if the game is launched normally.

If that did not work, end all the Battle.net and Warzone tasks in the system’s Task Manager. Then launch Vanguard and afterward, launch Warzone as administrator from the installation directory to check if that resolves the Warzone error at hand.

If the issue persists, check if launching another COD game and then switching to Warzone solves the problem.

Set Related Processes to Open as Administrator

1. Exit Warzone and close the Battle.net client.
2. Now make sure to end all the related processes in the system’s Task Manager.
3. Then, right-click on the Battle.net client shortcut and select Properties.

Delete the files in the Data Folder of the Installation Directory of Warzone

1. Firstly, exit Warzone and the Battle.net client.
2. Then, make sure to end all the processes related to Warzone and Battle.net in the Task Manager.
3. Then, navigate to the installation directory of Warzone like:

   C/Games/Call of Duty Modern Warfare

4. Now open:

   Data/data

5. Then sort the files by size and delete all the files having sizes 0 KB and 1KB (leave other files as it is).
6. Then launch Warzone from the Battle.net client and check if it is clear of the Blzbntbna00000012 error.
7. If not, check if deleting files less than 20KB in the Data/data folder of the Warzone installation directory solves the problem.

Disable UAC of Windows

Windows uses UAC to control access to protected and essential system files. If a Warzone or Battle.net process requires access to such a resource but does not have the required privileges, then it can cause Warzone Blzbntbna00000012 error. In such a case, disabling the Windows UAC may solve the problem.

Как исправить ошибку BLZBNTBNA00000012 в Battle.net?

Ошибка BLZBNTBNA00000012 очень сильно затронула игроков Call of Duty: Warzone. К сожалению, она держится уже около 1 месяца (начала появляться в 20-х числах декабря 2021 года). В ветке на Battle.net уже более 1200 сообщений с просьбой исправить ошибку, но официального ответа нет. Однако есть некоторые исправления, которые могут сработать у большой части пользователей. И все же часть не получают исправления. Не понятно, дело в том, что что-то сделано неправильно или не выполнено, или проблема в железе, регионе пользователей. Больше всего, что есть какой-то софт, который установлен на большинстве компьютеров. Например, известно, что у некоторых пользователей ошибка появилась после установки «Улучшение шрифтов Windows». После удаления все заработало.

Вот список эффективных способов исправления ошибки BLZBNTBNA00000012, хотя и не у всех, но у значительной части пользователей:

• Изменить регион. Почему-то ошибка может появляться при подключении к определенному серверу. Видимо, он в текущий момент времени может испытывать проблемы. Это делается очень просто – нажатием по изображению глобуса рядом с кнопкой запуска игры в Battle.net.
• Отключить атрибуты командной строки. Обычно срабатывает обратное действие, но в этом случае именно выключение. Нужно перейти в «Настройки» игры в Battle.net и выключаем опцию «Дополнительные аргументы командной строки».
• Убрать временные файлы. Можно их не удалять, а просто переименовать папку Call of Duty в разделе «Документы», добавив old или backup к названию. Также следует удалить временные данные для Battle.net. Для этого нужно перейти в AppData – Local и удалить «Blizzard Entertainment».
• Удалить программы. Особенно те, которые были установлены до тех пор, как начала появляться ошибка.
• Переустановить игру в корневую директорию. Помимо этого, также следует открыть папку с игрой и удалить все файлы, которые весят 0 Кб или 1 Кб. У некоторых это сработало.

Все остальное имеет крайне скромные шансы на успех, поэтому подобные способы мы не рассматриваем. Надеемся, что что-то из перечисленного сработает в борьбе с ошибкой Call of Duty: Warzone BLZBNTBNA00000012. Однако в какой-то степени она зависит от разработчиков и полного исправления до тех пор, пока они не займутся проблемой, возможно, найти не удастся. Все же самое актуальное находится на форуме Battle.net. Для тех, кто не получил облегчение, это единственный способ подобрать какое-то решение.
