I thought I'd remove the problem entirely by uninstalling CC2014.1 from my Mac… I chose to remove all preferences for for the application to ensure that no conflicts would occur in the future, and in doing so, Adobe Extension manager now has no applications in it that it can install an extension into. Flash, Photoshop, InDesign… everything has disappeared from the list on the left!
OK I thought, I'll uninstall DW CC too and then reinstall it to see if I can kick the applications back into the extension manager… perhaps there's just been a little glitch. Now I've uninstalled it DW CC, I can't locate from the creative cloud menu, so I can't reinstall it.
Any thoughts on this now?
