As of a few days ago, I have been unable to patch World of Warcraft and have been stuck at the initialising phase. After roughly 50 megabytes of progress on the initialising phase, it would reset until an eventual error message, requiring a restarting of Battle.net to start again.
Monitoring the situation through Task Manager, I could see that the Battle.net Update Agent background progress was terminating and restarting every time that a reset occurred.
I’ve deleted all Battle.net, Blizzard and World of Warcraft folders in the %APPDATA%, %LOCALAPPS%, %PROGRAMDATA% and %LOCALAPPDATA% folders.
I’ve located the Update Agent executable file and ran it as administrator.
I have done the same thing with Battle.net.
I have terminated every potentially conflicting app and background process that I am aware of.
I have included the Battle.net and World of Warcraft Program Files folders as exceptions in my security software, and I have even briefly deactivated my security software entirely when trying to update World of Warcraft and Battle.net.
None of the above worked.
Having attempted to reinstall World of Warcraft and Battle.net, this failed because of the pending updates that I could not download, so I chose to manually delete the Program Files folder for Battle.net.
When trying to install Battle.net, a similar issue occurs with installation progress resetting due to the Battle.net Update Agent background process constantly terminating and restarting itself, so now I am unable to install Battle.net.
As I’m unable to play World of Warcraft at this time, I’ve had no choice but to terminate my subscriptions.
Has anyone else run into any issues with the Battle.net Update Agent?
