Do not confuse this with the folder from Program Files (x86)! The fix for both of these issues is to delete the folder from the ProgramData directory (after closing the Blizzard application, and killing any Blizzard and Blizzard Update Agent processes). Clicking the force update button doesn't solve this. In some cases, gets stuck and refuses to install the update, displaying a ' Waiting on another installation or update' message indefinitely, even though there is no other update available for either or a game. The second issue occurs when a game has an update (it might be combined with having an update in the same time and updating first, but I'm not sure). I've been running into this issue quite frequently in the past few months. Restarting (and even the computer), trying to kill the Agent.exe process or every process related to doesn't get rid of this issue on my system.

Attempting to wake it up', with the BLZBNTBNA00000005 error code.

The first issue, and the most frequent one for me, is the Blizzard App Launcher () displaying a message that says ' Blizzard agent went to sleep.

Wow waiting on another installation
