Solution

I had the same problem and the resolution for me was running Volume Activation Tools with elevated privileges by right clicking the icon and selecting, run as administrator.

Until I did this I continually got an access denied error but after that it worked fine.

Hello,

I use the following command in an elevated cmd.exe:
cscript slmgr.vbs /ad-activation-online XXXXX-XXXXX-XXXXX-XXXXX-XXXXX "WindowsServer2016Datacenter"
