I'm trying to install .Net 3.5 on Windows 10 and I've found that there's no sources/sxs folder anywhere on my computer.Either that or I'm too stupid to find it . Even when I try to download .Net 3.5 through Windows Features on my Control panel it can't find the sources My internet is working fine and I've done that whole thing with the group policy editor so I have no idea where to go from here.

  • So mount a Windows 10 .ISO and point DISM to it instead of your local SxS, which if it is missing, means Windows will be unable to repair itself so that is a problem you should figure out. Of course the correct location is actually ../Windows/WinSxS/... not ../sources/sxs/.. – Ramhound Aug 17 '16 at 10:20

How did you install your Windows 10? If, for example, it was a USB drive with letter E: the following should be sufficient:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\sources\sxs

The file that needs to be in the sxs folder is called microsoft-windows-netfx3-ondemand-package.cab

A different trick is described on Technet: https://blogs.technet.microsoft.com/mniehaus/2015/08/31/adding-features-including-net-3-5-to-windows-10/

In a PowerShell administrator prompt use the following command:

Add-WindowsCapability –Online -Name NetFx3~~~~

Make sure the windows update service isn't disabled. The brain trusts here had it disabled via gpo
