Solution

There are some steps you may ensure to fix this issue:
  1. Make sure the required software for myRIO is installed. You can refer to article Required and Optional Software to Program NI myRIO for further information about myRIO software and download.
  2. Make sure the required software for programing myRIO is activated after the evaluation period. Refer to Activating NI Software Products for more information.
  3. If you installed the software components separately, that is, no using the LabVIEW myRIO Software Bundle installer, make sure you follow the correct order to install multiple NI software. Refer to Installation Order for Multiple NI Software Product.
