iTunes not recognizing itself via web app store, View in iTunes link not working

This is more of an iTunes issue but since it's relating to me downloading apps to my iPhone I thought I would start here.

So when I browse the web app store I used to see a "buy now" link and instead of that it says View in iTunes, when I click on that it wants me to install iTunes but I already have it installed.

Would anyone know why this would occur? I am posting this before attempting a complete reinstall of iTunes because I don't know if I would lose my iPhone backup by doing so. Essentially the app store doesn't recognize that I have iTunes installed.
