Yesterday, I got the new Nik 4.0.7 version and – as ‘promised’ – it deleted the previous Nik 3.3 version.
As I need the latest Nik 3.3 for my old PS ( optionally running with the first generation Selective Tool )
I tried a lot of back and forth …
The easiest way I found is to install Nik 4 as ‘recommended’ (no change in installation path), which erases all former Nik version. Then after I installed Nik 3 (= in the same path), which (also) re-adds the replaced Viveza 2 and Silver Efex Pro 2 programs. – Now, the ‘old’ plugins for PS and Affinity work again and PL4, when exporting to Nik Collection, shows …
I’m glad it was possible that way, otherwise I would have dumped Nik 4.
