Pro Opens Instead of Reader

[#1]

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.
