System.IO.FileNotFoundException was unhandled - Autodesk Navisworks API

I am referring to Nw_Single_Doc_With_View (written in C# .NET) in Navisworks 2016 API Training Labs.

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.

When I try to run the project, I got an error message saying:

System.IO.FileNotFoundException was unhandled Message: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll Additional information: Could not load file or assembly 'Autodesk.Navisworks.Controls, Version=14.0.1298.75, Culture=neutral, PublicKeyToken=d85e58fa5af9b484' or one of its dependencies. The system cannot find the file specified.

And when I try to view "Viewer.cs" [Design] page,I got an error message saying as followed:

For your info, my computer is a Windows 7 64 bit.

Could you tell me why I got this error and how can I solve it? Thank you

P/S: I have posted my question in Autodesk Navisworks forum here but there is no response so far.

Solution

  • I have solved my problem. Basically, you need to have a valid Navisworks licence on your computer. Then you can run the project smoothly.

    Previously I was using trial version of Navisworks and I got the error message saying "System.IO.FileNotFoundException was unhandled".
