I need to install .NET framework 3.5.1 on my brand new Windows Server 2012r2 standard machine.
I googled this to see how to do it. I launched the server manager. Did the role add and selected .NET framework 3.5. It gave an error about specifying a source so I clicked the advanced link and specified E:sourcessxs. E is my dvd drive. I had the Windows Server 2012r2 disk in the drive. The system ground away for over an hour and never got further than 46%. I stopped the process and rebooted the server.
I then launched an elevated command prompt and typed:
dism /online /enable-feature /Featurename:NetFx3 /all /Source:E:sourcessxs /LimitAccess. Again the 2012r2 disk was in the dvd drive (E). It got to 65.9% and ground away for 2 hours never finishing before I stopped it.
How do I Install .Net Framework 3.5.1 SP1 on this server ?
