I'm interested in developing a redistributable application using Labview that communicates with a USB device. I've used the application builder before for specific platforms. Is it possible with a single set of VIs to develop an application and use the executable builder to create executable versions for Windows XP, Windows 98, and Mac OS X? If so, do I need to buy the executable builder module for both Windows and Mac platforms? Does Labview 8 permit building executables for older operating systems such as Windows 98? (Windows XP is my development platform).
