missing itunesMobileDevice.dll

How do I find and reinstall this? I'm trying to run XCopyExpert and I keep getting the message.
Unable to load iTunesMobileDevice.dll Specified module could not be found Exception from HRESULT: 0x8007007E

I have uninstalled and installed iTunes to see if it would show up.

This all started when I wanted to copy from my iPod to my desktop. So help in that area is appreciated too.

Thanks

Try these steps:

1) Uninstall iTunes... make sure to uninstall ALL Apple software (Mobile Device, Update, Bonjour, etc)
2) Remove any remaining files in “C:\Program Files\Common Files\Apple”
3) Reboot your computer
4) Clean out registry for Apple dlls. You can used CCleaner.
5) Reboot your computer, again
6) Download last version iTunes from Apple, Reinstall it.
