title: Error Could not load file or assembly 'Interop.ActiveDs'
body: <p>I'm doing some active directory work with c# and I'm getting this error on my page</p>
  
  <pre><code>System.IO.FileNotFoundException: Could not load file or assembly 'Interop.ActiveDs, Version=1.0.0.0, Culture=neutral, PublicKeyToken=46db4b78e98e1c9d' or one of its dependencies. The system cannot find the file specified.
  </code></pre>
  
  <p>It's having some issue with the ActiveDS reference that was added
  I'm on a 64-bit machine and the server it runs on is also x64</p>
  
  <p>I added the ActiveDS reference so I could do something like this</p>
  
  <pre><code>newRoleGroup.Properties["groupType"].Value = ActiveDs.ADS_GROUP_TYPE_ENUM.ADS_GROUP_TYPE_UNIVERSAL_GROUP;
  </code></pre>
  
  <p>So my question is, why can't it load the ActiveDs reference?</p>
