Blizzard updating tools stuck

BLZBNTBTS0000005B Failed to run a required program. If this error reoccurs, please restart your computer and try again.
The first issue, and the most frequent one for me, is the Blizzard App Launcher (Battle.net) displaying a message that says "Blizzard agent went to sleep.
Attempting to wake it up", with the BLZBNTBNA00000005 error code.
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).
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.
Tech Support tried to help by giving me a myriad of fixes: dns flush, power cycle, Windows update, running a security scan, disabling security programs, enabling Secondary Logon, closing background applications, manually updating Agent, deleting Tools folder, and opening ports for all Blizzard games.
I think somethings wrong with it but I really do not have any idea how to fix it.
