abbodi1406 I followed the commands you provided to extract the files from the CAB archive. Then I used DISM.exe to add the ".mum" file to the system.
What needs to be done next to finish installing .NET 3.5? I don't see it listed as "Installed" when I run
Get-WindowsFeature
.When I try to install it from the Server Manager GUI, I get the error:
The parameter is incorrect. Error: 0x80070057

abbodi1406 Here is the result from running DISM to add the feature using the method you suggested.
dism /online /add-package /packagepath:C:\temp\netfx3\update.mum Deployment Image Servicing and Management tool Version: 10.0.17763.3406 Image Version: 10.0.17763.4499 Processing 1 of 1 - Adding package Microsoft-Windows-NetFx3-OnDemand-Package~31bf3856ad364e35~amd64~~10.0.17763.1 [==========================100.0%==========================] The operation completed successfully.
Yet, when I check my installed/enabled Windows Features
