System.IO.FileNotFoundException was unhandled - Autodesk Navisworks API
<p>I am referring to Nw_Single_Doc_With_View (written in C# .NET) in <a href="http://usa.autodesk.com/adsk/servlet/index?id=15024694&amp;siteID=123112" rel="nofollow noreferrer">Navisworks 2016 API Training Labs</a>.</p>

<p>I have added the Autodesk references DLL and set both of them as false in "Copy Local" property. Autodesk API Reference Manual has specified to set "Copy Local" property to false in DLL.</p>

<p>When I try to run the project, I got an error message saying:</p>

<blockquote>
