  • There may be issue with USB connection. Ensure that the iPhone is directly connected to a high speed USB 2.0 port on the computer and not plugged into a hub, keyboard, or monitor.
  • Try to install the apps via App Store on iPhone instead.
  • Delete the affected apps from iPhone (if it’s already installed), and try to re-sync.
  • Remove the application from iPhone (touch and hold the app, then tap the “x”) and from iTunes library (Right click and choose Delete, then remove and move the selected application to Trash or Recycle Bin.

    After clearing the device and iTunes from the apps which has problem installing, re-download and re-install the app.

  • Move the apps with error out from the “/iTunes/Mobile Application” folder, then restart iTunes and sync.
