The app is one of the most important tools for Blizzard’s fans. Thanks to this app, you can log in faster, communicate with other players, and strike off the task of updating your games – does it for you.

There are also instances when the app doesn’t properly work or stops working altogether. In this article, we’re going to focus on such an issue and offer you a quick workaround to fix startup crashes. crashes are very annoying because they prevent players from logging in. Usually, no error code appears, the app just freezes and then glitches out.

Here’s how one user describes this issue:

“After windows 10 loads afresh crashes at startup with an error until I manually launch C:ProgramDataBattle.netAgentAgent.5269Agent.exe
It started after the latest update i guess” crashes on startup [FIX]

  2. Clear cache
  3. Reinstall the client

Solution 1 – Change the intro configuration

1. Type %AppData% in the Search menu > hit Enter
2. Navigate to the “” folder usually located at this address:
3. Open the file using any text editor
4. Locate this line: “ShowIntroBalloon”: “false”,
5. Change it to: “ShowIntroBalloon”: “true”,
6. Save the config file > close it.

Solution 2 – Clear cache

1. Type run in the Search menu
2. Type %appdata% > hit Enter

If the workarounds listed above didn’t help you, try to manually open the app through the folder. If this works, this means that the launcher is the element that’s causing the crashing.
