There are some PDFs that don't render correctly. This seems to be due to the font, which can't be embedded into the PDF. Even if you have the type installed into the system, neoStampa won't use it to render the PDF.


The problem is solved if the user installs the font using the "Install for all users" option instead of "Install" in Windows using the context menu option. It is necessary to have administrative privileges.
