Windows 10 .Net 3.5

Maybe you know, maybe you don’t know, but Windows 10 ships with .Net 4.5.5

This is fine until you need to throw down an older app built for Windows 7 for example, basically anything Autodesk and HP SoftPaq Download Manager.

You will find yourself needing .Net 3.5 SP1 before you can install said application.  Some publishers, like Autodesk, ship their apps with a repository of pre-reqs, and some don’t.  This post is for those of us in the second boat.

What I’m about to show you might seem old and tedious, especially when you can just go grab the download in less time than it takes to read this post and do the action items, but I can promise you DISM has it’s place, for starters, in this blog post.  Side note: My boss used to make me apply all updates to our image using DISM only.  So think about that for a while.

Grab your Win 10 media and mount it.  Make note of the drive letter and file path (In the example, it’s D:\win10)

Open an elevated command prompt (right-click, run as administrator) and type:

dism /online /enable-feature /featurename:netfx3 /all /source:D:\win10\sources\sxs

Now you have what you need to install the older app!
