I've built my VI using a simulated USB-6218 DAQ device. Now I need to build the executable, with application builder, to be used in manufacturing where they don't have LabVIEW loaded, but they do have the USB-6218 available. I'm running LabVIEW 8.5. When I build the application and install it on the manufacturing computer, the non-DAQ features run correctly (ie LEDs respond, etc), but the USB-6218 does nothing. I've run the USB-6218 with the test panel in MAX on the manufacturing computer and it seems to respond correctly. Question is, how do I handle a simulated device so that the vi works on the real device after being compiled into an executeable? -Thanks.
