If your CommandFusion iViewer license is not working (or has stopped working for any reason) please follow these instructions:

1. Check that the Device ID used to register the device matches the one shown in our guiDesigner upload service window when you attempt to load your GUI - Retrieving your Device ID.
2. Check that you have added the registration code into your GUI and that you have saved the guiDesigner project before attempting to upload it to your device.

If the Device ID being shown in the guiDesigner Upload Service differs from the one you used to register your device, please submit a support ticket with the following information:

1. Old device ID
2. New Device ID
3. Email address the license is associated with

Then we can transfer the license for you.
