Yeah, I had never tried this under Windows and was going on the authors claim that it was working with Windows.

According to the README:
To install this module the SWI-Prolog executable "pl" has to be in the
+ PATH or alternatively the PL environment variable can be used to sel
+ect another executable name and location.

for windows understand 'pl' to mean 'plcon.exe' and
This module has been minimal tested under windows, it seems to work, a
+nd I plan to support it, but the primary development platform continu
+es to be Linux/Unix.

To make it work, the "bin" directory for your SWI-Prolog installation 
+will have to be included in your PATH also at runtime (If you get an 
+error telling about the lippl.dll being missing, try using 8 chars na
+mes in the PATH, i.e. C:\PROGRA~1\SWI-PR~1\BIN).
