Apple Mobile Service Failure

When trying to install itunes on my PC so i can put music on my new IPod Touch. I get an error reading. "Service 'Apple Moblile Device (Apple Mobile Device' Failed to start, verify that you have sufficient system priveleges to start system services." i went into my services to try and start it manualy but it says "Windows could not start the Apple Mobile Device service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion." idk what to do to sort it so any suggestions would be most appreciated.
