I have both Adobe Acrobat PRO DC and Adobe Reader installed on my computer. I have Adobe Reader DC set as my default program for PDFs, but starting this morning when I double-click a PDF it is opening in PRO instead of reader. Help!
Found from other threads. Under General in Preferences there is a [Set as Default PDF Handler] button in both programs. It was NOT on in Acrobat PRO. It was in Reader, but underneath it had an option "Always Open PDFS in Adobe Acrobat DC." I turned that off and now it works properly.
Unfortunately that button now just opens instructions for how to do it in Windows Apps/Default. Which does NOT work.
Found it: If you sign OUT of Acrobat DC, Reader as the defaut app works.
