You need to have NI-DAQ installed on the target computer to allow the program to run.
I think you can use LabVIEW`s VI-Server capabilities to allow for dynamic loading of VIs which do or do not rely on NI-DAQ, depending on the environment. If the NI-DAQ functions are "hard-wired" into your diagramm, these errors will occur. How to check for NI-DAQ Install without using a NI-DAQ VI I don`t know....
