Very frustrated. Just upgraded to Adobe Acrobat DC and I can't print when the program is open. Nothing happens when I click the print button; the printer dialogue box doesn't even open.
The workaround of right clicking on the file name and selecting print works, but not a long term solution. Hope this gets fixed quickly.
Running WIN10 and Adobe Acrobat DC 18.009.20050 on Surface Pro.
