Diagnostics

Every PC has its unique settings. In order to successfully use eSUN all the PC requirements have to be correctly configured. Additionally, network concerns outside of your control may affect your ability to use the eSUN system.
We highly recommend that you run the Diagnostics Wizard just to make sure everything is configured properly, and your network connection is suitable for the eSUN system.
