FireDac IBBackup Network Connection Error

I'm trying to deploy a small application to allow my users to backup and restore their local IBX database. The application works great on my development machine but when deployed, customers get the error "Unable to complete network request to host: localhost/3050". I added the line "gds_db 3050/tcp # InterBase Server" into the Services file. I have the following settings in the code for IBBackup

     Host := 'localhost';

     Protocol := ipLocal;

     DriverLink := FDPhysIBDriverLink1;

I looked all over online but can't seemed to find answers to solve this error on a local machine.

thank you
