PDFs require cloud sign-in and open in Acrobat DC Pro instead of opening default Acrobat Reader DC

[skagitt15740708]

First off this is not a default program setting issue.  The defaults for .pdf and .pdfxml on multiple machines are Acrobat Reader DC. However when I double click on a pdf from any of the multiple workstations I get a cloud login.  When I supply the login user/pass the pdf opens in Pro.  Even if I right click open with Acrobat Reader DC there is a login and it goes to Pro.

The only way I can get a pdf to open is to open Acrobat Reader DC and then File>>Open the pdf.

This started a few days ago and is system wide.

This will happen if Acrobat Pro is already running, even invisibly. So check in Task Manager for a running copy. But also check your Acrobat/Reader preferences, where the default app is set (as well as in Windows).
