Upgraded to Enterprise and Now I'm Getting a FileLoadException

[DieselPower]

I upgraded from 8.0.1 Standard to 8.1 Enterprise and now my application won't run.  I originally tried to use my existing project and when that didn't work I created a new project.

The exception is FileLoadException, and MSDN shows "The exception that is thrown when a managed assembly is found but cannot be loaded."

Attached to this post are two screen shots.  One shows the old project (created in 8.0.1) and one shows the new project (created in 8.1).  They both have the same error. 

Any ideas?

Hi Michael,

To help out, I need more information.  Some questions I have are:

• Can you run an example program?
• Did you uninstall 8.0.1 before you installed 8.1?
• Is there any other part of the error message, such as "Assembly Version Conflict."  If so, here is a reference:  Building a Measurement Studio Project in Visual Studio 2005 Results in Warning MSB3247: Found Confli...
• Are you using DAQmx in your project?  If so, this may help:  Deploying application which specifies DAQMx resource 
• If you run a new, project with just a very simple main(), does it throw this error?  If not, do you have an idea what line of code might be causing this error?

Turns out I needed a newer version of DAQmx.  Is there a way that I can include the most recent version of DAQmx in my installer?

Thanks!
