Hi, the error 1003 normally indicates a not runnable subVI. It wonder if the VI is running under LabVIEW 7 or if the error only occures when building an executable? Perhaps you can post your VI, so that I can check it on my computer? A few weeks ago, I had a similar problem running a LV6.1 VI under LV7. At that time the error was that the connections of a VISA-VI had changed, so that I had to wire one additional connection in LV7, but not in LV6.1.
