Attempting to use Segoe font in browser

I want to render a page with fonts mostly being font-family:"Segoe" (that line goes in the appropriate class selectors which I've verified are working), however I get back a standard f开发者_开发知识库ont (times new roman I think). Why won't it work? I am on Windows-7 64 bit so it's installed.

The name is "Segoe UI" not "Segoe". Change that and it will work.
