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.
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?
