Hi James,
The versions of the run-time engines and drivers on your target machine and development machine are important. They must match. Here is a KnowledgeBase that explain these conditions further. Since the error message is directly related to the existence of the VISA runtime engine on the target machine and you've confirmed that this runtime engine is installed, this may be the cause of the issue.
Try doing this:
1. Check the versions of VISA, DAQmx and LabVIEW (full and run-time) installed on both machines. Make certain they are the same. I do not see any DAQmx VIs in your program, but since you mentioned that you were also using DAQmx, you may want to check this, as well.
2. Open your VI on your development machine. Mass Compile it. This will update all of your VIs to the version of the drivers and LabVIEW installed on your system.
3. Build your executable with the Application Builder.
