My copy of Adobe Acrobat 2017 PRO began to disable the PDFmaker add-in for office applications in the last two weeks. There are a number of workaround suggestions on the net but none worked for me. As last resort, I uninstalled and shortly thereafter, re-installed. PDFmaker worked just fine....for a couple of days and then was disabled again. I tried uninstall/re-install again with similar results. In each re-install case I noticed that PDFmaker stopped working after the Feb 9, 2021 quarterly update (v17.011.301900). Today I did another unistall/re-install BUT this time I unchecked the automatic update feature in the preference settings. Let's see if this will prevent the disabling of PDFmaker.
