Had issues logging into wow today, wouldn’t let me connect to battle.net and appeared with BLZBNTBTS0000005C error, saying their was a problem updating Agent.
After trying the solutions re deleting Appdata, restarting, etc. I uninstalled battle.net and all battle.net games.
Now when I try to reinstall battle.net it gets to 45% progress, and comes up with the same error.
Really struggling to work out what my next steps are now beyond maybe reset PC.
Anyone got any ideas?
