What version of Acrobat (non subscription) do I need to automate Acrobat from Microsoft Office?...

Hi @Tim34399006izu9 

Adobe Acrobat Reader software is the free, trusted global standard for viewing, printing, signing, sharing, and annotating PDFs. It's the only PDF viewer that can open and interact with all types of PDF content – including forms and multimedia. And now, it’s connected to Adobe Document Cloud services – so you can work with PDFs on any device, from anywhere.
