Nik Collection can't work in PS

[翊唐黃74931654]

Photoshop version : CC 2018（Adobe Subscription Edition）

OS：Windows 7 Professional Edition

My Google Nik Collection filter has a problem like figure.

I'm sure it can normally work on my Macbook Pro.

I have tried uninstall and install again, but the problem still exists.

thanks!!!!!

This looks like some kind of highlight associated with a warning.

Look at the lower right corner where the Histogram is, and check if the Show Clipped Shadows or Show Clipped HIghlights is turned on. Those are the little boxes in the upper left and upper right of the histogram.
