How can i download bonjour?

support.apple.com/downloads/.

What country are you accessing that page from? I'm accessing from Hong Kong and I can't find Bonjour on that page. There's "Bonjour Print Services for Windows v2.0.2", but I don't think that's the full Bonjour service runtime. Last I heard, the Bonjour service runtime should be at version 3, and the Bonjour SDK should be at version 2.0.4; neither of them can be found on Apple - Support - Downloads.
