This really isn't enough info about your project to give a definative answer, but one possibility is that you could have set up your project to be statically linking to the MFC libraries which we don't support. It could be a lot of other possibilities also. If you would like, you could have our support engineers help you with the project by sending it to us via http://www.ni.com/ask.
