.NET Framework 2.0 and 3.5 feature install fails on Windows Server 2012 RC
Using Windows Server 2012 RC from the VHD, and selecting the .NET Frameork 3.5 Feature, gives error message "The source files could not be found". Downloading the install packages from the Internet, and attempting the install directly, gives error messages "Install from roles and features". Please advise

Hi,

Do you have access to internet with this machine ?

Using dism.exe should solve your problem if you have the ISO :

dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs /LimitAcces

Do have Internet access from the machine, but I don't get prompted for userid/password (it is an authenticated proxy)

Don't have the ISO. Downloaded the VHD rather than the ISO; don't really want to download another couple of GB

Negotiated an un-authenticated proxy and dism worked for me. Thanks for your help

I had to run it without limitacces.

dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs

Edit: I realized the right command was "dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs /LimitAccess"

Hello,

Do you have access to internet with this machine ?

Using dism.exe should solve your problem if you have ISO or the dvd in the machine :

step1

dism.exe /online/enable-feature/featurename:NetFX3/Source:D:\sources\sxs/LimitAccess

D:\ = drive or cd with the cabs maybe you have another leather

step 2

dism.exe /online/enable-feature/featurename:NetFX3 /all

after these steps i join to the domain

i did it in thease way

regards

Use the /all option if one of the parent features is not activated.

The operation is complete but NetFx3 feature was not enabled.
A required parent feature may not be enabled. You can use the /enable-feature /all option to automatically enable each parent feature from the following list. If the parent feature(s) are already enabled, refer to the log file for further diagnostics.

dism.exe /online /enable-feature /all /featurename:NetFX3 /Source:D:\sources\sxs /LimitAccess

@ Windows Server 2012 it worked with the /all option and without the /LimitAccess:

dism.exe /online /enable-feature /all /featurename:NetFX3 /Source:D:\sources\sxs

Deployment Image Servicing and Management tool
Version: 6.2.9200.16384

Image Version: 6.2.9200.16384

The operation completed successfully.

This works better when you put the command in correctly - it needs spaces - "dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs /LimitAccess"

When you add the spaces it works - don't forget to use an elevated powershell prompt (right-click the powershell icon and choose run as administrator).

I didn't need the second step - if you need it, don't forget to add spaces again - "dism.exe /online /enable-feature /featurename:NetFX3 /all"

Loose the quotes, of course.

Thanks for the hint - works great!!

Heh, this is a not_so_fun feature. It seems, that lot of stuff still requires 3.5, like Web server and SQL. I dont use installation media, I have vmware templates, and some times in data centers this could be a problematic thing to do.

Or you need to be aware of this, before creating the template and include 3.5 into the image.

You might face difficulty for installing .Netframework 3.5 on Windows Server 2012, where the Server Manager fails and tells you that due to the unavailability of the required source file for .NetFramework 3.5 it cannot continue the installation.

As a quick solution, you can use the below command for installing .Netframework 3.5, which requires you to amount the Windows Server 2012 installation media to the server.

C:\Windows\system32>dism.exe /enable-feature /all /featurename:NetFX3 /online /Source:d:\sources\sxs /LimitAccess
