title: Canon EDSDK Tutorial in C# "Canon Dll's not found" error
body: <p>I download the source only tutorial <a href="http://www.codeproject.com/Articles/688276/Canon-EDSDK-Tutorial-in-Csharp" rel="nofollow noreferrer">here</a>. When I run it with connect my Canon 70D, I got the error "Canon Dll's not found" shown below. After clicking OK, the gui appeared but all buttons are grayout on the gui. There is a folder name is 'EDSDKLib' in project folder. I am quite new at using canon SDK and I don't understand why I am getting the error. </p>
  
  <p>What is the reason of that? How can I solve it? </p>
