Hi, I’m having a similar issue but with the same error code. Just got a new PC yesterday, using Windows 11, Bnet downloaded just fine. I used the “locate the game” function on the Bnet launcher. It finds the game, says I need to update, but when I click on Update it gives me the blzbntagt00000840 error. I need help, please!
I’m still having this issue. Just sent the logs.
