Follow installer instructions. After installation, you should be able to execute WaveForms without registration.
Verify installation and connectivity:
Connect the Analog Discovery unit to your computer via the USB cable.
Launch the WaveForms application.
If your connection is successful, the device serial number will appear at bottom of WaveForms window. At this point, you may find it helpful to check out our Tutorials page.
If not successful, there will be an error message that there is no connection. In this case, you should try connecting your Analog Discovery unit to different USB ports on your computer to make sure that the issue is not with any particular USB port.Some support for installation troubleshooting may be found here, in the WaveForms 2015 Manual.
