Blizzard Update agent stopped working (BLZBNTBTS0000005C)

For the whole day i got BLZBNTBTS0000005C error when i try to lunch World of Warcraft. Can’t log in, so i can’t play and my playtime is being wasted. Worse- i can’t even reinstall battlenet, when i try i got an blizzard uninstaller stopped working. It also dosn’t work!

Tried the tips writed over here: https://eu.battle.net/support/pl/article/19031 but non of them works, and im sorry but i won’t belive the foult is on my side. Was playing 6h before trying to log in in the moring and game was working fine. Then i just shut down computer normally and suddenly i got this problem. I had read that there are some login problems, is this the same as all people? or do i have a diffrent problem? Can’t use the game i’m paying for.

Hello Scypio,

Sorry to hear about your issue.

Could you try out the following steps and see if this helps out?

  • Try adding the Battle.net app to the exception/exclusion list of your antivirus
  • Delete the Battle.net files/folders
  • In the Task Manager check if the Blizzard Update Agent is running, try ending the task there, and restarting the app.
