Hello, After some troubleshooting I was able to determine the problem I was experiencing was caused by our Anti-Virus's Active Protection.  Certain file types that are flagged with malicious risk, including .PDF, have a particular action taken against them behind the scenes.  This could still be an Adobe problem, so let me know if you have an AV that may be interfering with your Adobe. Some of you may have noticed Adobe flashes after opening, like it was deselected and re-selected. ... View more

gjuliana2017, We just discovered this issue today as well.  It seems like all our users with Adobe Acrobat Standard DC cannot print.  Just like others here, Page Setup and Properties buttons do not work.  I ran some tests, it appears about 1/10 attempts to print a document works.  I had to open a PDF, click Print, select Properties and see if anything comes up.  We use client licenses here, so it seems very unusual it's affecting all our users with Acrobat Standard DC installed. It appears that opening it and printing in Reader works every time.  There are no available updates that would help resolve the issue. I hope Adobe can get it together and have this fixed.  Talk about a major issue. ... View more
