Hello,
I’ve found the link https://support.dxo.com/hc/en-us/articles/4406551767825-DxO-PhotoLab-DxO-PureRAW-DxO-FilmPack-DxO-ViewPoint-compatibility-with-OSes-third-party-software but I haven’t found a information which Photolab Version is compatible or can interact with which versions of Viewpoint, Filmpack, Nic Collection.
I’m not sure if it is possible, for example to use PL6 with Nik4 or older Filmpack
best regards
Guenter
Good question Guenter
I am not aware of any backward compatibility problem between PhotoLab 6 and older DxO plugins.
Pascal
I am using PL6 with ViewPoint 3 quite happily. I don’t have any of the other plugins.
So do I.
No problems at all.
Hi Franky,
thanks a lot…would be a good gift for DXO 
Hello,
there are two pages in our FAQs concerning compatibility:
DxO PhotoLab, DxO ViewPoint, DxO FilmPack and DxO PureRAW
For each version of Nik Collection by DxO you can find all supported host software here
Hi Barbara,
thart’s correct and the first one of your links is the same I posted in the beginning of the thread 
.
But the description for example by the last tabel " DxO FilmPack & DxO ViewPoint compatibility with PhotoLab and third-party software" is wrong, because inside the table there is nothing with DXO PL.
In your second link i find “Nik Collection compatibility with DxO PhotoLab” and that’s obe of my questions
The information by Franky gave me the answer with one look
Enjoy coming weekend
Guenter
I remember that DxO used to show a table with the correct information. Something broke.
Something ???
