title: vscode installed in other directory gives access denied error
body: <p>I recently reinstalled my windows 10<br />
  For easy software management I chose to install all my software in the following directories:</p>
  <ul>
  <li><code>C:\Program Files\</code></li>
  <li><code>C:\Program Files (x86)</code></li>
  </ul>
  <p>This meant installing <code>vscode</code> and <code>vscode-insiders</code> on the <code>C:\Program Files\</code><br />
  instead of the default <code>C:\Users\User\AppData\...\</code></p>
  <p>However when I am working I get notified with the following popup:<br />
  <a href="https://i.stack.imgur.com/2STsM.png" rel="noreferrer"><img src="https://i.stack.imgur.com/2STsM.png" alt="Error, Access is denied" /></a></p>
  <p>clicking <strong>&gt; Try again</strong> gives the same popup instantly<br />
  clicking <strong>&gt; Cancel installation</strong> removes the popup for a short period<br />
  clicking <strong>&gt; Skip this file</strong> keeps giving kind of the same <em>access is denied</em> error</p>
