Do you have pictures selected?
Don't read German, but it appears the window you show is the Search Screen in Bridge. If you want to set up a collection you need to open Bridge, highlight your choices, click the Collections tab and in lower right corner choose New Collection.
the 2 Windows "search" and "new Smart collection" are exact the same exept the title.
"Suchen" is in english "search" and "Smart-Sammlung" is "Smart-Collection"
The Search function is working. no Problem.
I now how i must create Smart-Collections, i used in CS6 on the old PC with W7 and now i have a new one with W8 and i have make CC-Abo. But now it doesnt work.
It makes me crazy
Just to clarify, Photoshop CC has not been released yet. It will come out on June 17.
What you have now is Photoshop 13.x as per the subscription model (»Abo«) and it's called Photoshop CS6. When Photoshop 14.x is released on June 17, then it will be called "CC".
It's not clear—at least to me—which images, if any, you have selected in Bridge when you hit the »Speichern« (Save) button.
Remember that a Collection is nothing more than a saved search, i.e. a saved collection of selected search results (hits).
Could you elaborate on what it is you want to save as a collection?
Incidentally, the Adobe Bridge forum is here:
Has this ever been resolved for you? I transferred my Collections (Smart and standard) and preferences to a new computer with a brand new installation of Adobe CC. I can edit the existing Smart Collections I brought over, but cannot create a new one, as clicking the Save button darkens, but does not dismiss the dialog box. I can create standard collections though, with no problem. I didn't have that issue on the previous computer with the exact same collections.
This doesn't appear to be an OS or permissions issue, either. I'm on a Mac and having the exact same problem.
