Yup, that would be the problem.
Please refer to NI Switch Executive help file. You can run it on any machine that has NISE installed, from Start menu. Go to Programs>>National Instruments>>Switch Executive>>Documentation>>NI Switch Executive Help
There is a whole section on System Deployment that should be immediately visible in the Contents. Read through the "Preparing a Target Computer" topic, and you'll find all necessary steps to deploy your configuration.
I can tell you that you need to install the necessary drivers, port the NISE and IVI configurations, etc. but it is safest and fastest to go through that list in the help file as I may omit a detail or two here.
Let us know if it works though
best regards,
