WoW required an update last week. When that didn’t work it took me about 4 days to uninstall the Battlenet App. Now it won’t install anymore. It’s stuck on Updating Battle.net Agent.
Same problem. It stuck on update agent
Same. I found the .exe file for WoW so I can still run that, but neither Overwatch or Diablo III will run without Battlenet
Hi there folks!
So, there’s a few steps to try to resolve this for you, please do make sure to do them in order!
Firstly, please fully close the Blizzard App, and any Blizzard games, and then uninstall the App as per this guide:
Next, please delete all the Blizzard App files, some of which may be left over after uninstallation, by following this guide:
Finally, please download and install the App again via this link:
Once you’ve done that, please try running it again and sign in! You may find it does a number of updates, but that should hopefully fix things. 
Yours,

You can uninstall Battle.net with Revo Uninstaller.
- It creates Windows Restore Point.
- Uninstalls the program normally (the one you want obv.).
- Then scans for ALL leftover items including registry items related to program you’re uninstalling.
- So you can delete all leftovers of Battle.Net.
If you already uninstalled Battle.net normally through add/remove programs, then this won’t help.
It won’t be listed anymore in Revo Uninstaller so it can’t scan for leftovers.
