Poppler has worked with Helvetica for a very long time.  On Windows, it
should be mapped to the arial fonts.  I don't know why it's failing in
your case, but you could compile the source yourself and step through
the code to find why it's not working.  I would start with
SplashOutputDev::doUpdateFont in the file poppler/SplashOutputDev.cc
since I think that's where that error message comes from.

And no, we don't distribute binaries ourselves, only the source.  I
don't have much experience compiling things on Windows so I probably
won't be able to help with any compilation errors.  I understand cmake
is involved and lots of fiddling with dependencies, but not much else.
