My list of applications in Creative cloud includes pairs of several applications such as "Photoshop CC" and Photoshop CC (2014).
The same holds true for Illustrator and Dreamweaver.
Which is the most current version of the application and which version can or should be deleted?
This messages says (at least some) CC 2014 programs use NEW plugins https://forums.adobe.com/thread/1499663
-so do not uninstall the older CC programs if you use plugins in your programs until you are sure you have plugins that work in CC2014
If you are sure you don't need the old CC programs
