To install .NET framework 3.5 on Windows 7 Embedded, it is really a easy process once you know how to do it. This is an update to my previous post, I decided that I would make this one extremely easy to follow with step by step directions. My other post only worked occasionally, this one I've made sure it has worked every time that you do it. There are some files you will need before we proceed.
Chrome or Firefox to get the files you will need.
.net verification tool
The full .net 3.5 Framework
As you know with windows 7 how you would typically install the .net framework is though the add and remove programs. This is restricted in Windows 7 Embedded.
|To add .net 3.5 you typically go though the Programs and Features Category|
and select Turn Windows Features on or off
This post will by pass this restriction without doing any registry edits or messing around with security settings. For the rest of this post I will be working out of the downloads directory. I've already loaded chrome and have downloaded the .net verification tool and the Full full .net 3.5 Framework
open cmd prompt as administrator go to your downloads directory
and extract dotnetfx35.exe using command
You will get a prompt asking where you want to save the extracted files. I am saving it to a folder called net35
Once extracted we will need to go to net35 -> wcu -> dotNetFramework
You will then be prompted to save the extracted files. I've put mine in a folder called net35
Navigate to net35 -> wcu -> dotNetFramework
run the extract command in the command prompt again and save the extracted files to the same directory
inside of dotNetFX30 install the following files
This will install the essential files for .NET3, which is required before .NET3.5
Go up one directory level and go to the folder TOOLS and Install chwireg
Then go up a directory level find and run the setup application in compatibility mode vista sp1 and as administrator.
You can verifiy that .NET 3.5 SP1 has been installed by using the net_setupverifier
As you can see I have .NET 2 SP2, .NET 3 SP2 and .NET 3.5 SP1 all installed.
A couple other tools you may want to use or look at using once the frameworks are installed.
