Proximity Text, GLX, All Languages Update Loop

I am trying to update my maps, but first Garmin Express insist on updating the Proximity Text, GLX, All Languages to 3.90.

The D165900.zip is placed on the unit, but does not seem to ever complete the process.
I saw another post, which suggested removing the zip, trying again, and powering-up the unit for several minutes before reconnecting to the PC, removing the device from Garmin Express, and then readding.  This does not help.

Garmin Express says the update was "successful," but continues to insist that this update needs to be done.

I was able to update the language file.

How can I get the latest maps to install?
