Hello everyone,
If the regular uninstall doesn’t work, manually deleting the app should be enough. For that, please :
- Ensure not having any instance of the Battle.net.exe or agent.exe running (CTRL + SHIFT + esc, details tab)
- Delete the Battle.net folder (located by default in Program Files (x86))
- Delete the app cache
- Reinstall the app (in its default install location)
