Need to install Illustrator 2015
I want to install Illustrator 2015 but it is not showing up as expected in the CC Desktop app. I downloaded and can run 2017 thinking that I would need to do this in order for 2015 to show as a "previous version". I have done this on half a dozen other machines but the contextual menu I expect to see under previous versions for Illustrator is not showing up in CC. Am I missing a step on this one workstation? Running Mac Mini Yosemite OS currently.
