UPDATE: July 7th, 2015 – The Creative Cloud desktop app version 18.104.22.168 update is now available directly within the application, read on for how to check whether you have the latest version, if not you should be prompted to update or get a notification that it has updated.
At the time of writing the 22.214.171.124 release of the Creative Cloud desktop application which supports the installation of CC 2015 Add-ons as well providing various fixes, had not had the automatic update released. However, it is available to download and install from the Web, here (just click the download button to begin the download). So if you want to start using Add-ons and have the very latest CC 2015 apps, here’s what to do:
1. Check what version of the CC desktop app you have, (it’s like the one pictured above and lives in the top menu bar on a Mac and in the System tray on Windows). To check what version you have launch the CC desktop application and click the cog wheel in the top right hand corner and then click on Preferences as shown in the picture below:
2. Check what version you have installed, if it’s 126.96.36.199 (as shown below) or later you already have what you need for CC 2015 Add-ons compatibility for the CC 2015 June release. If you have an earlier version, get the latest version here.
