title: Getting the URL through `LegacyIAccessibleValue` fails on several computers
body: <p>I'm making a URL logging tool with UIAutomation. </p>
  
  <p>I could get URL from <code>LegacyIAccessibleValue</code>, so I thought I had completed the development. But getting the URL fails on some computers.</p>
  
  <p>And I found that <code>LegacyIAccessibleValue</code> and <code>ValueValue</code> are empty strings on those computers (check with Inspect.exe).</p>
  
  <p>For example:</p>
  
  <ul>
  <li>on some computers -> LegacyIAccessible.value : "<a href="https://www.google.com" rel="nofollow noreferrer">https://www.google.com</a>"  </li>
  <li>on some computers -> LegacyIAccessible.value : ""<br>
  (I cannot attach a file because of company security.)</li>
  </ul>
  
  <p>If anyone knows why then please tell me.</p>
  
  <p>Thanks for any clue.</p>
