Itunes not Reading iphone

Hey Guys,

My itunes is no longer reading my iphone, the computer is reading it as a camera. How ever my dads computer can read it fine.

I have reinstalled itunes about 5 or more times, i have tried to reinstall the drivers manually. I have forced my iphone into restore mode, But when it does this the computer fails to install the restore drivers and asks me to install a disc as it cant find any on the computer, yet they are on the computer. The main reason why i need to use my computer is because my restore file is on there and thats what i need
