ISSUE: Win2019 Server .Net 3.5

Question

I'm trying to setup and endpoint AV solution on its own 2019 VM. The software requires .Net 3.5.

On a clean Hyper-V installation of Windows 2019 Server, literally nothing else installed, .Net 3.5 fails to install. In fail I mean it halts and sits endlessly until I shut the VM down and I force it to restart.
I've attempted the installation by selecting .Net 3.5 as a Windows 2019 Role.
I've also downloaded a 240MB full install and tried it by specifying a local source folder.
No matter how I approach this the end result is the same, the progress bar goes about 1/2 way and stays there indefinitely.

Answer 1

You should insert installation media when you install .Net 3.5 by using Server Manager features,

Answer 2

You need an installation media, then specify an alternate source path to the installation media source\sxs folder, install.

Or, use dism /online /Add-Package /PackagePath:[sourcepath] command to offline install.

Answer 3

That makes sense. However, the original Windows 2019 installation was from a local image on a local drive to that VM. Would not the path to the installation source files be resident in that servers configuration for instances such as this?

Answer 4

You may need to send the sxs folder into a cloud storage, then download it in VM from cloud storage.

Answer 5

Okay, back at my desk. I'll give this a shot and let you know how it goes later today. 

This seems like a lot of consideration and work for something that should be very straightforward, aka the easy stuff.
