I have Windows-7. & LR-CC PS-CC. There is no choice for "Adobe-PDF" available to me.
Do I need a full suite of Adobe programs? for this to be available.
In the past I have had to rely on 'PrimoPDF' and recently 'Foxit-PDF creator', to create PDF files from any "Print" function in Lightroom.
Some users do this from the Slideshow module where there is an "Export to PDF" button - bottom left.
You don't need the full suite of Adobe applications. But apparently you at least need Adobe Acrobat. If you don't have it, then use the PDF option in the slideshow module.
