The most recent version of ScraperWiki depends on Poppler (or so the GitHub says). Unfortunately, it only specifies how to get it on macOS and Linux, not Windows.

Rumpel Stielzchen's comment:
This site is no longer maintained. Poppler version 0.68 is very outdated today. You find the latest version compiled also for Windows here: https://anaconda.org/conda-forge/poppler/files Sadly there is no 32 bit version, only 64 bit

Latest Poppler Windows binaries can be found here:
