I have now looked at the project and identified the problem.
You have always referred to the file being created as
_ns.pdf. It is in fact _nc.pdf.
After various attempts I generated an output without a skin.
Problem stopped.
Then I created a new skin and a button for the PDF, still no
problem.
Then I looked at your button and noticed it points to a file
PDF\UserGuideAmadeus.pdf whereas the filename is
PDF\userguideamadeus.pdf. Note the different case.
I think what is happening is that RH notes the different case
and wants to create a file with the case corrected. On a Windows
machine that would not be possible so it appends _nc for Name
Change.
Correct the button on your skin and the problem should go
away.
