I have been at this for days! All my extensions are gone. I updated CC Apps to the 2015 version, but I don't like them so I went back to the CC 2014.1 version of Dreamweaver, but now my extensions don't work. Not only that, but when I open the Extension Manager (and yes it is the correct version for cc 2014) Dreamweaver, Photoshop, Illustrator do not show up on the left side, all it says is Other. When I go to reinstall my extensions, I get the "This extension can not be installed, it requires Dreamweaver version 9 or greater".
I have uninstalled and reinstalled everything (not the extensions because they don't show up on the manager), I've gone and reinstalled from my backup...I've looked on a million forums...nothing is working!!! Very frustrating!
