my workflow on windows 7 was managing the photos with Zoner Photo Studio version 16- then sending the picture from with : open with to lightroom.
up to lightroom version 5.4 there never was a problem. Now with Version 5.6 it doesn´t work. After unistalling 5.6 now 5.4 doesn´t work also. I think there´s a problem in the registry .
Does anyone know this problem?
Lightroom opens Lightroom-catalog files (.lrcat extension) not photos. Once LR is open with a catalog, then you import a photo.
In other words you shouldn’t be able to assign an “open with” to LR for a photo file, only an .lrcat file.
