How do I install .NET 4 on Windows Server 2008 R2 from the command line or PowerShell?

This post shows how to do it for .NET 3.5 using dism.exe and PowerShell. I am guessing that, since the .NET 4.0 binaries need to be downloaded first, these instructions do not work for .NET 4.

Do you mean 2008 R2? Or do you actually mean RC2 as in a release candidate? – Ryan Bolger May 31 '11 at 16:20
R2 - sorry about that – house9 Jun 1 '11 at 20:55

Your question might get more views if you edit it to fix the mistake. You should also probably update your windows-server-2008 tag to windows-server-2008-r2. – Ryan Bolger Jun 1 '11 at 23:39

I have done the following in Powershell:

((new-object net.webclient).DownloadFile("http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe","dotNetFx40_Full_x86_x64.exe")) 
& .\dotNetFx40_Full_x86_x64.exe /q

There are other command line options than /q (for quiet). You can see those by doing:

& .\dotNetFx40_Full_x86_x64.exe /?

This isn't specific to powershell, but might be of help. After installing .NET3.5 we follow up using the full install binaries, simply running a silent install. Depending on what and how you install this may require a reboot.

This how I've run silent installs of .NET4 in build/update scripts on 2003-2008R2 servers using the full install package:

  • dotNetFx40_Full_x86_x64.exe /q

If you've not already stumbled across these, you might find them useful:
