Just as I was in the middle of installing iTunes my computer locked up. I rebooted and ran the installation again only to be presented with the following error after plugging in my phone:
A quick reinstall of iTunes left me in the same boat. It turns out that you have to remove several Apple products in a specific order before reinstalling iTunes. So open up your Control Panel then uninstall these components in the following order:
-
iTunes
- QuickTime
- Apple Software Update
- Apple Mobile Device Support
- Bonjour
- Apple Application Support*
At this point you can now install the newest iTunes and you should be able to sync your iPhone without any issues.
*iTunes 9 or later

Thank’s Bro. It work
It worked. only your solution worked.
This article is from 2009, and it still works in 2025. This was the ONLY way I was able to get iTunes working for me, since I needed to use a specific older version of it and no matter what I did, it had this error continuously. Thank you very much.
Glad to hear it’s still helping people out!
