I'm a rookie at posting in the Forum. I posted the message below as a reply to a previous post but, here it is again. I'm trying to figure out a problem with my S4 now. I will share the details later but, for now, does anyone have a link to download the older S4 Driver Version 3.0.0. I would like to try this driver as I'm using the Version 2.9xxxx I was able to download it from NI back in December as a zip file. Today, I unzipped it and tried to run the install. Half way through the install and I get a warning for something like network error. Whatever that means, I don't care. I figure the zip file is corrupt. I checked NI downloads but driver V. 3.0.0 doesnt seem to exist on the list of downloads any longer.
