Hiawatha was designed for Linux / BSD, not for Windows. I made a Windows version available because it was very easy to do because with
Cygwin [www.cygwin.com]. But that version is not intended as a production version. If you really want to use all Hiawatha features on a Windows machine, my advice is to install Cygwin, compile Hiawatha manually with Cygwin and also use it from within Cygwin.
