Windows SP3 installation - "The system cannot find the file specified."

Trying to install Windows SP3 (Network Installation) on a client machine. It would not install, giving the error message "The system cannot find the file specified." and "The installation could not complete"

Thank you to DataOne on the softwaretipsandtricks.com forum which pointed me in the right direction.
