title: NUnit "could not load file or assemby 'MyTestProject'
body: <p>I'm setting up a new 64 bit machine to run as a build server.  When I try to load my NUnit test assembly into NUnit GUI I get the following error.</p>
  
  <p>There is nothing obvious missing, all the dependencies seem to be present. All the DLLs are compiled for the x86 platform.</p>
  
  <p>Using NUnit 2.4.7.  I have tried upgrading to 2.4.8 but the same error occurs.</p>
  
  <blockquote>
    <p>System.IO.FileNotFoundException: Could
    not load file or assembly
    'MyTestProject' or one of it's
    dependencies. The system cannot find
    the file specified.</p>
  </blockquote>
  
  <p>System.IO.FileNotFoundException...</p>
