At NI, we understand that in some situations our software is the best choice for a limited time project or maybe your company wants to reduce the overall cost of ownership. In these cases, we offer application software as a subscription. Subscription software includes the same convenient benefits of our perpetual software, only the functionality expires after one year. You must renew your subscription to keep working in the software. When you renew your subscription, you will not only be able to keep working; but also, receive any new software updates released.
