Where do I find the Bonjour service I need for home sharing from a Windows 7 desktop?

For general advice see Troubleshooting issues with iTunes for Windows updates. Start with Install missing components.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with third party software.

Your library should be unaffected by these steps but there also links to backup and recovery advice should it be needed.

Historically the iTunes installer has installed this along with iTunes itself. I say historically because it is so long ago since I did a fresh install of iTunes on a fresh Windows machine so it might be the case this has changed.

However there is still a separate Bonjour installer you could run just in case this is needed. This is more typically used to access Bonjour advertised printers. See - Download Bonjour Print Services for Windows v2.0.2

Are you using the Remote app by Apple on the iOS devices?

If your iOS device isn't showing in iTunes try the following:

1. Open Control Panel > Device Manager
2. Plug in your device
3. Locate Universal Serial Bus Controllers > Apple Mobile Device USB Driver.
   It is also possible the device may show under Imaging Devices, Portable Devices or Other Devices or as an MTB USB Device.
4. Right-click and select Update Driver Software...
5. Click Browse my computer for driver software
6. Browse to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers or
   C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers
7. Click Let me pick from a list of device drivers on my computer
8. Click Apple Mobile Device USB Driver
9. Click Next, then Close and exit Device Manager

For step 3 above, open the device manager. Expand any of these sections that are listed.

• Universal Serial Bus Controllers
• Imaging Devices
• Portable Devices
• Other Devices

Connect the device. You should hear the telltale sound of Windows device connection and one section should gain a new entry. That should be your device. It may not be labelled correctly at this stage. If you don't hear a noise suspect a damaged cable.

Or try If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support which is Apple's version of the advice above.

Failing that try a full tear down and rebuild of iTunes as set out in Troubleshooting issues with iTunes for Windows updates. 64-bit users could also try the alternate Download iTunes for Windows (64-bit - for older video cards) build which is sometimes a useful workaround.

Or lastly try rolling back to the last build of iTunes that worked for you. See iTunes installers for download links. If you're rolling back from 12.4.0.119 to 12.3.3.17 or 12.3.2.35, for example, then you'll also need to roll back the library database using the method described in Empty/corrupt iTunes library after upgrade/crash. The tip includes suggestions for reintroducing any recent purchases so at worst you lose a few playcounts and/or a recently created playlist.

Read the notes below the second box. try stopping services, reboot into safe mode, or the unlocker utility.

I'd recommend installing the current version if possible. If it really won't reinstall try the next most recent build.. Rolling your library back to one compatible with an older version causes a different set of problems.

1. There is a section in the user tip on this error. The install may not have completed successfully. Try repairing Bonjour from the programs and features control panel.

2. Try holding ctrl+shift when launching iTunes which opens it in safe mode. Doing this once may have a positive impact on subsequent launches. Also try right-clicking on the shortcut and using Run as administrator. Desktop or task bar short cuts may be out of date.
3. Advice on reinstalling/updating drivers as given earlier.
4. Check home sharing settings. If they appear to be set correctly turn off, then turn back on again.
