I have AP 1.8.3. It does not recognize that I have the NIK collection. I tried going to the directory where it is located from within AP, but it does not recognize that the NIK exe file is in the directory where it is. Use of the NIK collection is critical for me. I see that others are having these problems too. If I cannot get AP to see the NIK file, this is a deal breaker. I will not even use AP for free, let alone $25. By the way, I could not find where to post this message, so I am doing it here. The layout for your forums is horrible. Where the hell do we post just simple, "I am having an issue with Affinity Photo" questions?
