The driver is what is most important. The "interface" is what is used to create the DSN (data-source-name) that is used by FileMaker with ODBC to external sources. If you do not see the ActualTech driver, then you need to use the other app/utility. If you find that you cannot see a created DSN in the FileMaker dialog, then you need to delete this DSN and use the other app/utility to create it.
I have tested to import from the external source and it is working except that it only works on the first 3 rows until I but a license.
