Endnote Not available prompt

Hi, I just started using End Note few days ago. I am using Word 2016. Below is a capture of the prompt I keep getting whenever I want to update my citations and biblography. It is so annoying, anybody with advice on how to deal with this?



desktop or endnote online?  If desktop, is the correct ribbon selected?  See the image – endnote ribbon, preferences, application.  from the drop down, endnote (desktop) vs endnote online (online version).
