I've just got around to updating my Photoshop CC 2015 and noticed that my Nik collection doesn't show up now. Do I need to install it again?
Simple Windows procedure copied and pasted from elsewhere, but not recommended by Adobe:
It is installed in a different location
In File Manager go to here:-
c:\Program Files\Adobe\Adobe Photoshop CC 2015
and copy the whole PLUGIN and PRESET Folders
then go to the folder below it:-
c:\Program Files\Adobe\Adobe Photoshop CC 2015.5
and simply paste them in
Your filters and licenses will be transferred
and all (after a very quick inspection) will be as it should be
