body: <p><em>Win32 SmartDevice DLL project - VS 2008</em></p>
  
  <p>I'm trying to use the <code>ICaptureGraphBuilder2</code> interface, but when I try to create the istance using the following code:</p>
  
  <pre><code>CComPtr&lt;ICaptureGraphBuilder2&gt; pCaptureGraphBuilder;
  hr = pCaptureGraphBuilder.CoCreateInstance(CLSID_CaptureGraphBuilder);
  </code></pre>
  
  <p><code>hr</code> is <code>0x80040154</code>.<br></p>
  
  <p>How can I solve this problem?</p>
