title: How do I detect if XenApp Client is installed on user machine?
body: <p>We are upgrading from Citrix Metaframe to XenApp, and I need to know if there's a way to programmatically detect if the XenApp Web Plugin v11.0 is already installed on a client machine when it contacts our webserver for login -- this was previously done for the Metaframe Web Client by attempting to instantiate the ICA client in an ASP script, which used the results to determine whether to offer the client as a download/install.</p>
  
  <p>The current code for this detection is:</p>
  
  <pre><code>Set icaObj = CreateObject("Citrix.ICAClient")
  </code></pre>
  
  <p>The above code does not find the XenApp plugin. </p>
