I am getting a license error message when I select the PCB Editor menu: Export > PDF. 


PDF > Export is a feature that is added back into OrCAD/Allegro PCB Editor. It is available in OrCAD/Allegro 17.2 ISR65 (released March 20, 2020) and is included with OrCAD/Allegro 17.4  ISR5 (released April 3, 2020).  This PDF output is intelligent and provides more capabilities than the version that was released earlier.

Users need to download the latest hotfix to get this functionality.
