Install .NET 4 via command line or PowerShell?
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.
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
