TIP: For this download to work automatically, certain OpenSSL
libraries must be present in your system.  United States export laws
forbid the inclusion of OpenSSL libraries in our installer package.
However, you may install them yourself.  For Windows you can get an
approved package here:
http://slproweb.com/products/Win32OpenSSL.html. You will need at least
the *Win32 v1.0.2j Light* package. Take the default options in the
installer, particularly the option to install into the Windows system
directory.
