title: Failure encrypting web.config using RSA and file path
body: <p>I am using the following command in order to encrypt a file </p>
  
  <pre><code>aspnet_regiis -pef "connectionStrings" "d:\MyPath\web.config"
  </code></pre>
  
  <p>I get the following answer </p>
  
  <pre><code>The configuration for physical path 'd:\MyPath\web.config' 
  cannot be opened.
  Failed!
  </code></pre>
  
  <p>The file is not in a read only mode and I run cmd with admin privileges.</p>
  
  <p>Any Idea? </p>
