Some of the more common reasons for this include, but not limited to, (a) your device (iPhone, iPad or iPod) does not have enough storage space for this update/download (b) you are experiencing network, internet connection issues or (c) your device does not meet the minimum iOS version requirement, e.g. the app requires iOS 5 or later but your device is running iOS 4.
