Could not load file or assembly %27NationalInstruments.Vision%2C Version%3D10.0.35.101%2C Culture%3Dneutral%2C PublicKeyToken%3D18cbae0f9955702a%27 or one of its dependencies. The system cannot find the file specified.

I'm trying to write a .Net app that references the NI dlls.  I can reference the dlls fine and access the objects therein but, when I run my app and try to execute code in the dll's I get a "file not found" error.  I tried running Visual Studio as administrator but, that has no affect.  I can run the example apps that came with the NI software just fine. 

Visual Studio 2008; .Net 3.5; Windows 7 OS

Thanks.
