The Bonjour network service enables computers to automatically discover and connect to other devices that are on the same network. It's provided by default on the Mac OS X operating system, but you have to install it manually if you are using a Windows computer.

If you do not have Bonjour installed, Composite can't discover your computer and will not be able to connect to Photoshop®.

How to install Bonjour

To install Bonjour on your computer, you need to download either QuickTime or iTunes for Windows. If you have either of these installed, Bonjour is probably already installed on your computer.
