After trying several different things this is what seemed to "fix" the problem:  I went into Windows Device Manager and deleted the Bluetooth Wireless device (and marked the checkbox to delete the driver software too).  Then I rebooted the PC.  Magically the device was back with installed driver 22.30.0.4.  Now when I run  SupportAssist nothing is flagged as needing an update and it looks fine now.  So, I guess it's fixed.
Fails near the end of the download of about 24 Mbyte Intel download.  I've retried several times and re-booted my PC (Dell Optiplex 7780 AIO) to no avail.  It is the only critical update in the list.
