Hello I am currently developing a LV software which includes communication to an external device via a serial port.. I am using the NI VISA Configure Serial port and NI VISA write tools.. Everything works fine, as a LV project.. However, after building a exectuable and installer, I tried it out and it didnt work.. SO my question is, is there an additional setting or source file that I need to include for the serial communciation to work on the executable or installer? Thanks Von
