Any update includes all changes in previous updates. So, for After Effects, you just need to install the 12.2 update.
I have seen reports of needing to uninstall and reinstall the Creative Cloud desktop application to get it to see recent updates. [*grrrr*]

Todd,
I am on Creative Cloud and Mac OS 10.8.5 and it looks like After Effects (and other Adobe apps for the matter) is stuck on version 12.0.0.404.
Neither Creative Cloud desktop nor Help/Updates work for updating AE. So I am going to try to download directly the update. Do you know if I can update directly to 12.2 update or do I have to download all the incremental updates?
