Hey there,

So this error indicates the update agent for the desktop application is unable to perform a needed task. This could be due to a connection issue, corruption with the desktop app itself or interference from something else on the system. The following steps should help you out.

Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:

We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.

Let’s manually clear the Battlenet Desktop Application and all supporting data from the system. This will not remove existing game clients.

1. Open file explorer/file manager (Right Click Windows Start)
2. Navigate to the folder where the desktop application would normally be installed. Delete that folder if it exists (usually program files x86)
3. Type the following into the address bar (not the search bar): %APPDATA% and press enter.
4. Delete the Bnet and blizzard folders inside the appdata folder if they exist.
5. Repeat steps 3 and 4 with %PROGRAMDATA% %LOCALAPPDATA% and %TEMP%
6. Empty the recycle bin.
7. Now reinstall the app to the C: Drive.

Try running your system in selective startup mode: https://battle.net/support/article/200483

Create a new administrator account: Blizzard Support - Creating a New Administrator Account

Once the account is created, shut down the computer, wait 60 seconds, restart, log into the new profile and try the app/client.
