Do I need to install Bonjour to use the Tobii Pro Analytics SDK 3.0 ?

Yes, Bonjour is required. The core library in the Tobii Pro Analytics SDK depends on dnssd.dll and will refuse to load unless it is present.

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.
