Q: Bonjour

Hi ABlickensderfer,

One way to reinstall Bonjour is to install (or if necessary reinstall) iTunes for Windows. You can tell if Bonjour is already installed using the methods on this page -

This page tells you that the Bonjour install is part of iTunes for Windows -

iTunes for Windows: Background processes installed on Windows XP, Vista, and 7

And the iTunes for Windows installer may be downloaded here -

Apple - iTunes - Download iTunes Now

Thanks for using Apple Support Communities.

Best,

Brett L
