是的，Bonjour是必须安装的。Tobii Pro Analytics SDK的核心需要使用dnssd.dll文件，如果没有则会导致SDK加载失败。
Bonjour installs (at least) two things on the computer
- A Windows service that listens for Bonjour devices on the network. This one is called "bonjour.exe".
- And a dynamic-link library, dnssd.dll, that is used by applications that want to know about available Bonjour devices.
