iPhone apps not transferring
Some of the purchased items on the iPhone "(name)'s iPhone" could not be transferred to your iTunes library because you are not authorized for them on this computer.
I have tried authorizing my computer (with the message that my computer is already authorized) and going to File > Transfer purchases from iPhone and syncing my iPhone and computer but nothing seems to be able to transfer some of my apps from my iPhone to my Library.
I do not have the latest update installed to my iPhone because a message comes up saying that some of my purchases are not transferred to my library and should be before the new software is installed.
Any help or suggestions would be greatly appreciated!!!
PC, Windows Vista
