Unable to install .Net 3.5 on a new Windows 10 install

I had similar issues, turned out W10 had it installed already. Try your install without it.

dism sxs fails? That's ugly...

Have you seen this (blocking GPO)? http://superuser.com/questions/946988/cant-install-net-3-5-on-windows-10#comment1449644_947660

Edit: Won't help I think. GPO is about loading additional dependencies directly from Windows Update. Shouldn't relate to offline sxs.

That GPO would make sure that MS servers were contacted. I set it anyway. no difference online or media.

@JaredBusch yeah, sorry, realized it the second after hitting "submit".

Still not able to install? Any errors in the event log?

Not worth the time to figure out anymore. Told Windows to reset. Do not have physical access right now.

Windows reset completed, enabled .Net 35 first, worked perfectly.

Up yours Microsoft.

I'm pretty sure when I had this issue, sfc /scannow did the trick.
It was a while ago though...

That GPO Never seems to work..

@jaredbusch, 1803 fresh install doing the same thing, fresh iso downloaded via latest Media Creation Tool for the source location.
Tried numerous options including an installer program, a command line to install a specified package, and copying the sxs folder locally instead of mounted iso.

nadnerB's suggestion to run sfc didn't do anything, but runnings DISM /Online /Cleanup-Image /RestoreHealth appears to have done the trick. Net 3.5 finally installed successfully and didn't require a reset and repeat of 3 hours' setup.

I wonder if you could grab the cab file without needing to get it from the iso

https://github.com/Microsoft/dotnet-framework-docker/blob/master/3.5/runtime/windowsservercore-ltsc2016/Dockerfile

the download URI used in the script does seem to be specific to ltsc2016, but I wonder if that matters
