On a Mac:
Check the Applications folder > Adobe Photoshop CC 2017 folder > Plug-Ins folder > Google folder to be sure you have a folder containing each of your Nik Plug-Ins.
Then be sure you go to Lightroom>Preferences>External Editing and set up each plug-in there.
Also, if you use the Nik tools stand-alone apps, they should be in the Applications folder > Nik Collection folder.
Burkphoto - thank you for your persistence. Nik is now working for me. Thanks for your help!
