No, the functionality of the profiles was not added by Adobe until April 2018 (or else we would have released them years ago) and will not work in versions earlier than Lightroom Classic CC 7.3. If you check your Develop panel and see the Profile section at the top of the Basic panel (by default,) then the profiles will work. If you see the Profile section at the bottom of the Develop panel (by default) then you need to update to install and use The Archetype Process. We can’t recommend the awesomeness of theAdobe Creative Cloud Photography Planenough though!
