title: Failed to install ad-hoc distribution with itunes 11.0.1
body: <p>I have strange problem. I developed app code signed it with Distribution provisioning profile which includes correct devices and sent it to Client. He installed via iTunes and there were no problems. Suddenly iTunes 11 was released and Client told me that he is unable to install app on his devices.</p>
  
  <p>The situations looks like this:</p>
  
  <ul>
  <li>authorizing computer </li>
  <li>adding app to iTunes library </li>
  <li>selecting app to sync/install on device </li>
  <li>start synchronization</li>
  </ul>
  
  <p>Synchronization goes to step 4 where message says thet apps to synchronization are prepared and synchronization ends showing in iTunes that app is installed on device. But on device there is no app. No error or any kind of message, nothing...</p>
  
  <p>To make things more complicated I'm able to install app on my devices (I even borrowed iPad's, iPhones and one iPod touch from friends to check it). Although I'm not able to install it on one iPod Touch 4G. The app is compatible with iOS 5 and 6.</p>
  
  <p>Any ideas?</p>
