Thank you Roy
Can you please do the following
Click start, control panel, programs, uninstall a program
Uninstall the below software in the following order. Then, restart your computer.
Apple Software Update
Apple Mobile Device Support
Apple Application Support (iTunes 9 or later)
Once you have restarted, install iTunes again from my link belowhttp://www.apple.com/itunes/download
Once done, it should then work.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Let me know the results please
