Recently updated from Acrobat Reader DC to Acrobat Pro 2020; can no longer preview PDFs in Outlook

[Office2390946247gt]

My work machine was recently updated from Acrobat Reader DC to Acrobat Pro 2020.  As a consequence of this, I am no longer able to preview PDF attachments... I get the "this file cannot be previewed because there is no previewer installed for it"

Some hopefully useful info:

 - I'm using 64-bit Outlook, and I'm using Adobe Acrobat Pro 2020 (version 2020.005.30334)

 - I also noticed in Outlook's Trust Center that I don't have a PDF previewer listed in the Attachment and Document Previewers list. (screenshot attached)

What's the fix to get my the PDF preview functionality back in Outlook?  Thanks!
