C# & Windows Update Api (WUApiLib)
<p>I am using Windows Update API (WUApiLib) in a C# .NET 2.0 project.</p>

<p>I get the following error on Windows XP (in Windows 7 it works alright): </p>

<p><strong>"System.MissingMethodException: Method not found: 'WUApiLib.UpdateSearcher WUApiLib.UpdateSessionClass.CreateUpdateSearcher()'."</strong></p>

<p>This is my code:</p>

<pre><code>WUApiLib.UpdateSessionClass session = new WUApiLib.UpdateSessionClass();
WUApiLib.IUpdateSearcher searcher = session.CreateUpdateSearcher();
WUApiLib.ISearchResult result = searcher.Search("Type='Software'");

if (result.Updates.Count &gt; 0)
{
    //do stuff
}
</code></pre>

<p>The error occurs at runtime, the compiler shows no errors...</p>

<p>Does anybody know why I get this error?</p>
