title: How to upgrade typescript to version 1.7?
body: <p>I have <strong>Visual Studio 2015</strong> installed on my computer. Under the folder <strong>C:\Program Files (x86)\Microsoft SDKs\TypeScript</strong>, I see two directories</p>
  
  <ul>
  <li>1.0</li>
  <li>1.6</li>
  </ul>
  
  <p>When I use the command <strong>tsc -v</strong>, I see version <strong>1.0.3.0</strong>.</p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>Is the version 1.0.3.0 really typescript version 1.6?</li>
  <li>How can I update my computer to <strong>Typescript 1.7</strong>?</li>
  </ol>
