Download from the Microsoft Download Center
Since the launch of the NAV 2017 , Microsoft has changed the way you download the cumulative updates . Before the launch, you had to enter your e-mail, wait for a reply mail, and then download the updates from a link in the received mail. Now the updates are available from the Microsoft Download Center, which makes sense, as it is also here you find updates for many other Microsoft products.
Cumulative Update 01 includes all applications and platforms corrections and regulated features that have been released for Microsoft Dynamics NAV 2017.
