Despite multi uninstalls/reinstalls/re-downloads/etc. on my MAC running High Sierra 10.13.5 I get this message every time I call up Nik from the filter menu in PS:
Could not complete the Color Efex Pro 4 command because of a problem with the filter module interface.
Then nothing happens. PS doesn’t crash anymore at this point. The installs of Nik have gone smoothly. I have downloaded your latest version as of this morning. The plug-ins seem to be working OK in LR CC. I need to be able to use CEP4 on selections in PS. I rarely use it on a full image in LR! Help?
