The Network Synchronizer is only necessary if your attempting to sync though your local WiFi using Moneydance 2014 or earlier. We've dropped support for WiFi syncing since there are issues that cannot be fixed due to certain network configurations over which we have no control.
All syncing to mobile devices is now done though Dropbox. Dropbox syncing is end-to-end encrypted, meaning that all your data is encrypted between your Moneydance application and your Moneydance iOS app, with none of it being unencrypted on your Dropbox folder. For these reasons, we've stopped maintaining the WiFi syncing functionality and are unable to fix most problems with it.
You should be able to follow the instructions on this page to set up syncing between Moneydance 2017 and your mobile device.
Please let me know if I can be of further assistance.
