Nik DXO collection version


I have a licensed (purchased in June 2019) Nik Collection. How can I determine what version I have and if not the most current, how do I update.


Launch one of them as standalone e.g ColorEfexPro.
Click on the Icon in the top right. This brings up the ‘About’ dialogue

So in my case I have the Google NIK version etc

Not sure about the Update part though.
