Executable built from a vi containg Median Filter.vi runs on server with LV Run Time Engine 7.1 installed. Running this executable from a desktop by a shortcut pointing to the executable on the server gives "Load Error 21 subroutine not found". LV 7.0 did not give this problem. Same problem if use Real FFT instead. No DAQ or VISA involved - only this one vi. lvanlys.dll is present in executable folder.
