title: CLR20r3 Exception
body: <p>I wrote a small C# app. Installed it in the admin account. It worked fine.</p>
  
  <p>When I tried to execute it from a non-Admin account and another Admin account, it threw an error. </p>
  
  <pre><code>CLR20r3 System.Security.Security Exception
  </code></pre>
  
  <p>and the application stopped working.</p>
  
  <p>What can be the issue?</p>
  
  <p>Thanks</p>
