I'm running Illustrator CC 2015 (version 19.1.0). Just purchased the Smart Layer Export extension from the creative.adobe.com/addons site, and it wouldn't install via the Creative Cloud App. Per the page's alternate installation instructions, I tried installing the extension via Adobe Extension Manager CC, but when I do so, I get an error saying the extension cannot be installed because it requires Illustrator version 16.0 or higher.
Any suggestions on how to resolve this?
