So yesterday I decided to download Heroes of the Storm again, but my Battle.net was stuck at calculating space and then going blank with installation window, so I thought of doing a reinstallation of a Battle.net desktop app and it only went downwards from then onward.

Uninstalling was completed easily. Then, when I tried installing again the window got stuck at 'Updating Battle.net Update Agent' at approx 40-50% of the bar. Then after another few dozen tries it changed to showing ' BLZBNTAGT000008FC' error after being stuck on 40-50% of Updating Battle.net Update Agent.

3. Use Archive Utility to extract the installer. Cached data in your modem and router can cause installation failures. Power cycle your connection hardware. Run a security scan to remove any viruses or malware infections. Update or temporarily uninstall any security programs, which may mistake the installer for a threat.

Now, I’ve been searching the forums far and wide and some things.
I’ve killed agent.exe before trying again.
I’ve cleared all temporary folders from Battle.net and Blizzard Entertainment folders.
I’ve cleared %ProgramData%.
I’ve reset WMI repository - which is recommended for shown error.
I’ve tried using no antivirus (honestly having to uninstall it instead of adding something to exceptions should never be required).

Nothing helped. I did try to rollback entire Windows10 back to yesterday before I started trying to download HOTS, but all I got now is “Required application data could not be found” system error.

So now I can’t play Starcraft II that was working perfectly before I tried to have fun with friends in HOTS and I am left with nothing but a broken Battle.net desktop app that seems to be beyond possibility of repair.

Is there anything I could try?
