Nothing will update or install

BLZBNTAGT00000BC9

I’m getting this error when trying to patch any game on the app, and despite optimising WiFI, reinstalling the games and the app, forcing the Agent to reinstall still no luck. I’d chalk it down to server/maintenance issues but everyone on my friend list is still playing, and the few I asked have not had any similar issues.

Hey Blake,

Can you try a full reinstall of the Blizzard app?

  1. Uninstall the Blizzard app

  2. Next press Windows Key + R and enter the following locations and delete any Battlenet and Blizzard folders in each location:
    • %LOCALAPPDATA%
    • %APPDATA%
    • %TEMP%
    • %PROGRAMDATA%

  3. Finally go ahead and reinstall the app from here. Make sure you run as Admin.

If that doesn’t work, try testing another network like a mobile hotspot or free VPN to see if there’s any change.
