Knowledge Base FAQ Item #7780152

Q7780152: When I create a new Graph, I get an error: "The following feature couldn't be installed: .NET Framework 3.5.". But when I try to install this feature from the Server Manager, I need to specify an alternate source path.

In recent Operating Systems, including Windows Server 2016 and Windows Server 2019, the .NET Framework 3.5 installation files are NOT included in the Operating System. You need the Windows Server installation media (usually a CD-ROM, or .ISO image).

To install .NET Framework 3.5, please take the following steps:

• Mount the Windows Server installation media (DVD or .ISO)
• Start a new Command Prompt in Administration mode
• Type: Powershell
• Type: Install-WindowsFeature Net-Framework-Core -source "D:\sources\sxs"
  where D: is the DVD drive. (viewed: 252)
