Glad you were saved the hassle of re-installing iTunes by not removing the AppleMobileDeviceHelper program.
Here's the route to finding the iTunes program file:
C:\Program Files\iTunes
When in the iTunes folder, look for the iTunes program [around 19.3 mb),
click once to select it [not twice], then right click for choices, and select "run as administrator" . Good luck.
