For Office 2016 version, the program is available to register. I have tried to do it manually and auto registration both ways without success. After the attempt while attempting to change it to auto-registration, KMS server window will be displaying that the license is already on the list.
The best way to activate products from the KMS server is to activate the product in the background. Then, when you exit from the application and re-open it the license will be activated for that computer automatically, you don't need to do anything else. 827ec27edc
