WOW wont install

[Crash-12156]

I cant install wow because i keep getting this error BLZBNTAGT0000084B and it says “We couldn’t access a folder. This is usually because you’re not logged in as an administrator.” I have had wow installed before and have never had this issue before would like some help. Also I am on windows 10.

Hey there,

Thank you for taking the time to report this! Update errors like this one are typically caused by a conflicting third-party program, damaged/corrupted local Battle.net files, or a problem connecting to the patching server. Try the following steps to narrow this down:

1. Fully update or temporarily uninstall Antivirus or similar security programs which may be interfering with your connection to the server. If you’d like more information on troubleshooting security applications, click here

2. Reinstall the Battle.net Desktop App with these steps:

   • Uninstall the Blizzard Battle.net App (skip Step 6 for now, we will re-install later).

   • Next (before re-installing) let’s delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders in the Windows temporary file locations below. If you don’t see all 3 folders in each location, that is okay—just delete the folders you have):

   • Press Windows Key + R and type: %LOCALAPPDATA%. Delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders.
   • Repeat the process for %APPDATA%, %TEMP%, and %PROGRAMDATA%. Delete any Battle.net, Blizzard, and/or Blizzard Entertainment folders.

   • Finally, re-install the App.

If the error persists, many potential problems related to your installation of Windows can be resolved by creating a new administrator account, logging into it, and testing on the new account.

If the issue is fixed on the new Admin account, this could indicate damaged or missing Windows system files or an issue with how the old user account is configured. This is somewhat common, and the easiest fix is to move any user-specific files that you wish to keep from the old user account to the new admin account. You can also work with Microsoft’s Support to troubleshoot the problem with the old account if preferred.

If the problem continues, temporarily test a different network such as a mobile hotspot to determine whether the problem is isolated to your current network.

Hopefully, one of these steps will do the trick. Please let us know if you have any questions or run into additional issues.
