I haven't any problems communicating with the TC 32 when I'm on the development computer, it's only when I load my program on to another computer using the installer that I made in LabVIEW that the problem comes up. My LabVIEW Program runs fine but the TC-32 never poles. Both computers have the latest version of Instacal and they are both Windows 10 computers. The problem has something to do with the Ulx files when they are loaded into the Installer.
