After a recent update to Microsoft Windows 10 the PDF24 program most of you use for sending PDFs from inside JMS stopped working.
The team at PDF24 have fixed this issue in version 9.2.0
To update PDF24, open it and in the grey bar at the bottom should be "Check for Updates" click this and it should talk you through updating the program. If that doesn't work visit the PDF24 website (https://tools.pdf24.org/en/creator) and download it from there.
If installing from the website deselect the option "Register PDF" when running the setup, otherwise it will become your default PDF.
