When attempting to update the firmware in a DS3678-ER scanner connected via a STB3678 cradle I keep getting the error message -

Last activity on this scanner was unsuccessful.
Error details: The firmware selected does not match the target scanner.

123Scan reports the following current firmware and update.

Existing:     Release 002 - 2017.01.24 (SAACKS00-003-R00)
Update to:  Release 004 - 2018.05.17 (SAACK00-004-R02)

All the release notes appear to confirm that this is the correct update for this model scanner so I was wondering if anyone had any suggestions on to resolve this stale mate.  Extra detail below.
