Although this used to work in the past, I am no longer able to save a book as PDF.
I have tried with a simple test book with a single one page file.
When I ask to save as PDF, Framemaker seems to work but then nothing happen : no error, no file created.
When I ask to print using Adobe PDF printer, I get an error saying : « Impossible to print because default printer not compatible with Framemaker (Cannot qurey command escape 768) » (this is a translation from the French error message).
However, I may ask to print to « Microsoft print to PDF » printer. It works.
I have Acrobat Pro DC version 2018 installed. But it seems Distiller is never used.
