2) another possible cause is that the destination folder or files are locked for some reason.

1) To resolve the issue for the moment, the user right-clicked the 'Database Load Utility' link and selected the "Run as Administrator" option. The files then loaded ok.
The MSP user will speak to their IT people about changing the permissions needed for future access to the MSP Postal Reference files' location.

For problem cause 2) rebooting the system resolved the problem, and the DB files loaded normally.
