Why am I am receiving the message “XXXX is not a Keysight generated command set." when downloading command sets?

This defect has been fixed in Command Expert 1.1 Update 1 and later.

The method used to verify the authenticity of the Keysight command set has expired. This does not impact the functionality of the command set. Click “Yes” and the command set will be installed and is fully functional. You can also upgrade to the latest version of Command Expert to automatically resolve this problem.
