Acrobat preflight tool not working
In Acrobat Pro DC (2015 release) with the Print Production tools loaded, the Preflight tool has stopped working.
Output Preview works, but when selecting the Preflight icon, nothing happens, no dialog box.
Did the usual checks, update CC, restart MacOS Sierra 10.12.
I have Acrobat XI and that still works.
What is wrong with Acrobat Pro DC?
