Hi John, Doesn’t seem to be a problem here on Windows 10 and my Plugins are setup like this without moving the actual plugins into the default directory for AP (excepting NIK Collection):
It seems unusual as for the Unknown it just means “untested” or “Possible incompatibility”
Just check you have your plugins the same as this because it will pick up the first in the directories, and as Topaz Studio comes last it’s plugins aren’t picked up:
Also, I subsequently observed that it is not a question of AFP finding the Impression plugin…it does. Because when I temporarily move the plugin out of it’s home folder, and restart AFP, then Impression no longer shows up in the filter menu. So, that tells me that AFP is finding the plugin where it expects to.
