title: How to use Gecko engine in ABCPDF v7 Classic ASP
body: <p>We have just moved an old website to a new hosting company who has ABCPDF version 7 installed on a Windows Server 2012 VPS.</p>
  
  <p>Unfortunately the existing code is not working and from my research it is due to version 7 not being compatible with later versions of IE, such as that installed on Server 2012.</p>
  
  <p>So I was trying to switch to use the Gecko engine. I installed Firefox on the server. And added the code to the Classic ASP script straight after the doc object was created:</p>
  
  <pre><code>doc.HtmlOptions.Engine = 1
  </code></pre>
  
  <p>Unfortunately this results in the following error:</p>
  
  <pre><code>Object doesn't support this property or method: 'HtmlOptions.Engine'
  </code></pre>
  
  <p>How can I change to use the Gecko engine, and am I doing this right or is there some other issue?</p>
  
  <p>As a last resort is it possible to install an older version of IE on Server 2012?</p>
