iphone not recognized by Windows 7

iPhone 4 no longer recognized by Windows 7, 64-bit desktop. The iTunes diagnostic shows everything working satisfactorily, and Windows Control Panel, under Devices and Printers, shows the "Apple Mobile Device USB Driver". The Properties for that device show the driver as working properly. However, when I plug the iPhone into a USB port (using both a port and cable that formerly worked fine with this iPhone), Windows attempts to install a driver, and fails. The resulting message is "MTP USB Device Device driver software was not successfully installed". Further investigation gives me a message "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".

Like some of the people above, I didn't have the problematic Registry Entry. After some searching, I found this article. It is one of the best articles on how to fix this annoying problem (obviously Microsoft's idea of messing with Apple).

Note: Windows 7 Enterprise 64bit. iphone 4S. iTunes 10.6.3.25


While it didn't exactly describe how to fix my issue, it helped point me in the right direction. Here is what did to fix my issue.


1. Open up Device Manager

2. Portable Devices > Apple iPhone (in my case had an exclamation point on it)

3. Uninstall the driver.

4. Right click on the the computer in Device Manger and scan for hardware changes.

5. Go back to Portable Devices. If this works for you, the Apple iPhone icon should not have any exclamation points any longer and it will be accessible via My Computer.


Good Luck.
