"Apple Mobile Device" failed to start. Verify that you have sufficient privileges to start system services.. then options to retry, abort or continue without installing component

After using this computer for 7 months (bought it new last November) and iTunes worked perfectly well until one day it stopped displaying the device option( the one that shows what iPhone or I pad..etc you got connected) and then you can sync the devices. but this went missing and iTunes could not re-download it. 
I have contacted Apple support and gone through all options to remove and re-download iTunes.. but didn't' work. Each time, after downloading most of the programme - it stops to give the following message:
iTunes: Service 'Apple Mobile Device' (apple Mobile Device) failed to start. Verify that you have sufficient privileges to start system services."
Please help
