when trying to compile a PDF output using the “proofing” option I get this error message:
PDF file could not be created
There was a problem creating the PDF file using the “Proofing” option,
which uses a third-party library to generate the PDF data. Would you
like to create the PDF file using Scrivener’s standard methods? (This
is the same as using the “Publishing” option.)
This behaviour did not appear before today.
What is that “third-party library” and where can I find or get it?
All the best
