Nik installer dumps a lot of things all over your Mac and the uninstaller is completely helpless when several accounts are used as I have on my machine… It also helps to make visible the hidden items with shift-command-period. Careful in what you delete though!
I’ve reported the places where I found Nik artifacts in this forum, good luck with search
