iPhone 5 not connecting to iTunes?

Hello all!

I am using an iPhone 5, and upon trying to connect it to iTunes, i get the message "This iPhone cannot be used because the software is not installed. Run the iTunes installer to remove iTunes, then install the 64 bit version of iTunes." I've uninstalled iTunes already, reinstalled and have been given the same message. I'm running windows 7, and iTunes 11.0.1.12. I'm not really sure where to go from here, any help would be appreciated. Sorry if it's a simple fix and seems like a silly question!
