hello gingernob and welcome to the free 4images forum,
thank you for your statement. very nice that you teach us, what is good for the 4images success.
4images is working on Unix and as well on Windows IIS environment.
of course if you have mySQL, PHP, GD/ImageMagick installed on your Windows host.
chmod commands will not work..
so, read steps: 1,2,3,4, 6,7,8 from 4images\docs\Installation.english.txt and everything will work fine for you.
if you need more help, you can always come back to us with your issues.
have a nice day!
