Hi there! I recently bought a laptop with Windows 7 OS. I've already installed the latest Quicktime and iTunes 64 bit version and they work fine. However, when I hook up my iPad to it, iTunes keeps telling me that "This iPad cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes, then install the 64 bit version of iTunes". I've reinstalled everything but it still doesn't work. Help!
