P: Nik DFine2 hanging in Sierra

I don't use DFine, Sharpener or Viveza anymore, but I do use CEP, SEP, and Analog. Those last 3 have been running all along without any problems beyond the occasional crash.  Testing now, DFine runs, but so slowly, it may as well not. Sharpener Pro runs, but is slow to preview. Viveza also runs, but painfully slowly. All of these tend to "stutter." That is, for a moment they speed up, but then balk again. DFine is far and away the worst, but I wouldn't want to use any of them if I didn't have to. I should say I'm in 1.0 now.

I tested them all in 2015 and there's no issue with them whatsoever. Google is giving Nik away for free now, so I seriously doubt it will update any of them. I can say, though, it's not the OS (I'm still running Yosemite) and it's not the computer. It's between Adobe and Nik and those 3 plugins. Well, I don't use HDR, but it works fine on a single image—just tested.

Hi Kees, 

Sorry for the freezing with DFine2. Were you running CC 2017.0.1 before this update?
Was the DFine2 plug-in working OK in that version?

On the Nik page, the system requirements for the plugin don't show compatibility for CC 2017, so hard to tell if the plug-in has been updated or not.

Have you tried going through the general troubleshooting steps yet?

Resetting the preferences may be good step to start with. 

Let us know how that goes.
