Cannot PRINT to Adobe PDF from any program after reboot UNLESS Acrobat has been started at least ONCE for the current session. Perhpas this is because Acrobat has not "signed in" or authenticated as a licensed app until AFTER I have opened Acrobat? This has only been occurring recently within the last few months. The credentials are and have always been "saved" such that I am automatically authenticated when I open Acrobat. I am licensed for CC All Apps Annual. I am using Windows 10 64bit on a less-than-a-year-old Dell Inspiron i8 with 32GB RAM and 2TB drive.
