My installation seems incomplete - why are Nik applications missing from the program folder? (Windows only)

This information applies to versions 6 and newer (Windows only)

The plugins in question are not missing: their location simply changed for technical reasons. By default, this folder is located in:

C:/Program Files/DxO/Nik Collection/bin

As of Nik Collection 7, Nik Perspective (formerly called Perspective Efex) is no longer part of the Nik Collection.
