Adobe Reader DC updated to Continuous Release 2020.012.20048 (File version 20.012.20048.6926). I open a SCANNED PDF and immediately get error reading:
A font package is required to correctly display this page. Click "OK" to direct your browser to download the add-on from adobe.com. After installation, you will need to close and re-open the document to correctly view contents dependent on these newly installed fonts.

I click OK and eventually get directed to: https://supportdownloads.adobe.com/thankyou.jsp?ftpID=6839&fileID=6837

This page has a "Download Now" button but when clicked does nothing - no download is initiated and I get no warning of a popup being blocked.

Please fix! Reader DC will not even properly print a scanned PDF. Pages just print blank.
