I am trying to create a smart PDF of my board. However, I am getting an error regarding a license when I select Export > PDF.  How can I resolve this issue? 



This has been a known issue. A hotfix that enhances the smart PDF generation is available in a hotfix you need to download and install from the Cadence Download Manager. The hotfixes for OrCAD/Allegro 17.2 ISR65 were released March 20, 2020 and are built into OrCAD/Allegro 17.4  ISR5 was released April 3, 2020. 

The PDF generated is intelligent and provides more capabilities than the previous versions.
