title: How can I add an Access DB to my C# project when it requires an MDW file too?
body: <p>I want to use an Access database file in my C# project. When I add it as a new Data Source all goes well until I try to test the connection. Then I get the message:</p>
  
  <pre><code>Cannot start your application. The workgroup information file is missing or opened exclusively by another user.
  </code></pre>
  
  <p>The file is password protected and an MDW file is used. So how can I add the file as a data source and use the workgroup info file as well?</p>
  
  <p>Thanks</p>
