title: Can't deploy universal app to phone with Windows 10 Mobile Tech Preview
body: <p>I have a developer unlocked <strong>Lumia 635</strong> just yesterday updated to <a href="http://windows.microsoft.com/en-us/windows/preview-download-phone">Windows 10 Mobile Technical Preview</a> (OS version: <strong>10.0.12562.84</strong>).</p>
  
  <p>After creating "Blank App (Windows Universal)" targeting <strong>Windows Phone 10</strong> in Visual Studio 2015 RC and tried to deploy it to the device (and have changed configuration to ARM for that exactly purpose) I've got this error:</p>
  
  <blockquote>
    <p>Error : DEP0001 : Unexpected Error: A Prerequisite for an install could not be satisfied. (Exception from HRESULT: 0x80073CFD)</p>
  </blockquote>
  
  <p><strike>
  After quick look at the app "references" it is turns out there are some of them specific to <em>Application Insights</em> (and few others) with disregard to the fact that I've specifically <strong>unchecked</strong> the <em>Application Insights</em> integration on project creation dialog before (surprise!). So I've removed them all leaving only the following (seems like unremovable):</p>
  
  <ol>
  <li>Analyzes</li>
  <li>.NET for Windows Store apps</li>
  <li>Windows Universal</li>
  </ol>
  
  <p>But this didn't help, unfortunately - still can't deploy this "default" app to the phone. 
  </strike></p>
  
  <p>Though, deployment of my current working universal app that target <strong>Windows Phone 8.1</strong>, to this phone was just flawless.</p>

  Working OS is <em>Windows 8.1 Pro</em>, if that matter.
