title: How do I install TypeScript?
body: <p>I have version 0.9.1.1. So I ran the following:</p>
  
  <pre><code>C:\test&gt;npm install -g typescript
  npm http GET https://registry.npmjs.org/typescript
  npm http 200 https://registry.npmjs.org/typescript
  npm http GET https://registry.npmjs.org/typescript/-/typescript-1.0.0.tgz
  npm http 200 https://registry.npmjs.org/typescript/-/typescript-1.0.0.tgz
  C:\Users\david\AppData\Roaming\npm\tsc -&gt; C:\Users\david\AppData\Roaming\npm\nod
  e_modules\typescript\bin\tsc
  typescript@1.0.0 C:\Users\david\AppData\Roaming\npm\node_modules\typescript
  </code></pre>
  
  <p>But when I run tsc I get:</p>
  
  <pre><code>C:\test&gt;tsc
  Version 0.9.1.1
  Syntax:   tsc [options] [file ..]
  </code></pre>
  
  <p>What else do I need to do to install the latest version?</p>
  
  <p><strong>Update:</strong></p>
  
  <pre><code>C:\test&gt;where tsc
  C:\Program Files (x86)\Microsoft SDKs\TypeScript\tsc.exe
  C:\Program Files (x86)\Microsoft SDKs\TypeScript\tsc.js
  C:\Users\david\AppData\Roaming\npm\tsc
  C:\Users\david\AppData\Roaming\npm\tsc.cmd
  </code></pre>
  
  <p>tsc.exe is 0.9.1.1 and tsc.cmd is 1.0.0.0</p>
  
  <p>I then removed the VisualStudio 0.9.1.1 AddIn and it's now all good - just tsc.cmd and that's 1.0.0.0</p>
  
  <p>Thank you all!</p>
