title: Unable to activate windows app store - Install failed(VS 2015, UWP)
body: <p>I try to debug a UWP app that I developed, using UWP in VS 2015 Enterprise..
  When I try to run it , I get the following message:<br>
  "Unable to activate windows store app (app name). The activation request failed with error 'Install failed'. Please contact your software vendor.</p>
  
  <p>I know the question was asked before, I try the following:</p>
  
  <ul>
  <li>Uninstall the app</li>
  <li>Unistall VS</li>
  <li>PC restart</li>
  <li>Deleting all the build directories</li>
  </ul>
  
  <p>Moreover, I checked and the app temporary file were created in<br>
  C:\Users(My User)\AppData\Local\Packages(App name)....</p>
  
  <p>Any ideas?</p>
