I have the exact same problem as this person,
https://community.native-instruments.com/discussion/19201/kontakt-7-vst3-error-fl-studio.
However while I believe the response to that question is the solution, my native access does not have a VST3 destination in the file management.
Ive reinstalled the Native Access application twice, reinstalled Kontakt 7 twice, I am doing circles at this point.
