Running texi2any on Windows to generate HTML

Any advice on how to get a working instance of texi2any on Windows would be
most welcome. I began a project on my Mac at home, but when I got to work,
where we use only Windows computers, I was unable to find a texinfo install
for windows that include texi2any.

I was able to install a working version of texinfo from gnuwin32, but it
seems to lack texi2any. I was able to run makeinfo --html, but while it
runs, gives me lots of errors (along the lines of "`A' has no Up field
(perhaps incorrect sectioning?).") which I don't understand and didn't
appear when using texi2any.
