This work, thank you.

I found the following article's Method 2 option worked in both Windows Server 2012 R2 and Windows Server 2016 images provided by AliCloud - [url=http://.Net 3.5 Installation Error Guide]https://support.microsoft.com/en-us/help/2734782/.net-framework-3.5-installation-error-0x800f0906,-0x800f081f,-0x800f0907[/url]  


It was a difficult one to resolve and no matter how you provide the AliCloud system with SxS files, the OS will reject them if it is not allowed to use Windows Update or a specified other source, it would seem.
