title: Provisioning profile error while installing custom enterprise app on iPhone
body: <p>I have developed an iPhone enterprise app for a client.</p>
  
  <p>The application is working properly on all devices, however, on one user's device, the application installation gives an error
  <code>Unable to download application. &lt;Application name&gt; could not be installed</code>.</p>
  
  <p>This error message comes up while the application icon shows the installation progress.</p>
  
  <p>On further investigation, we found that the enterprise distribution profile is not being installed and the following logs are seen in the console.</p>
