Are you attempting to use the Battle.net app on an unsupported platform? It currently supports Windows and Mac only.
Some security apps will also disable the updater agent, like MalwareBytes.

I’m having the same issue and i’ve tried everything it says. It doesn’t work at all.
I was running everything just fine until tonight.
Been using for 6 years on this computer, started yesterday after an electric outage.
I m on windows 10.
I tried it, doesnt work. Also tried to uninstall bnet but it wont uninstall. How do i uninstall bnet app?
Was in the same boat as you guys until I reset my WMI repository by finding another post that I can’t post a link to, but you can find a article by searching “blizzard resetting the wmi repository” The forum post told me to do it safe mode and the article doesn’t so I’m not sure safe mode is needed but it fixed the issue for me. Do you guys also have “allow multiple instances of battlenet” enabled? Curious if this error if these problems are due to that, although it has been working fine for me for months.
Worked for me Tvvvm
