I have DXO Filmpack 5 Elite, Nik Collection 3 and DXO Viewpoint 3, all of which have been superseded by later numbered versions. I am currently using DXO Photolab 4 Elite.
I do NOT wish to upgrade Filmpack, Viewpoint or Nik Collection, but am interested in upgrading to Photolab 6 Elite.
Question: will my earlier versions of Filmpack, Viewpoint and Nik Collection referred to above work with Photolab 6 Elite?
It’s another case of figuring out where to look.
The Nik Collection 3 User’s Guide (can still be downloaded from support.dxo.com) specifies that compatible host applications include PhotoLab 2 and newer. I can think of no reason why PL6 wouldn’t support it. Even if it didn’t, you could still choose “Export to Application” and specify the path to the executable.
You can still use Nik Collection 3 though. Export the files and open them with the Nik app of your choice. It’s less convenient, but might save you a few headaches because you know exactly how Nik3 behaves.
However, as I read the tables given in the links above it appears Photolab 5 and Photolab 6 continue to remain compatible with Adobe products from 2019 and 2020.
I bought Nik Collection 3 in 2020 (I think) and it is DXO’s OWN PRODUCT. Why is NIK Collection 3 not similarly compatible?
They seem to integrate the same as they always have on PL6. So I can’t say anything for sure for your Filmpack5, but for Viewpoint3 at least an upgrade is not needed.
