I would like to use a third party installer (Q-Setup) for a stand-alone application I recently built using LabVIEW 7.1. The program was developed to run on Windows XP/2000/98 and requires serial communication with multiple devices. I realize LabVIEW and VISA RT Engines are required for this application, but am unsure if there will be issues with using a third party installer especially for builds across the different windows platforms (i.e., different RT engines for different platforms). The Application Builder provides options to 'silently' install the RT engines without problems, but I would really like to use a third-party installer. If anyone can provide some feedback about how best to include the RT engines using a third-party installer, I would greatly appreciate it. Thanks.
