Can't install .NET Framework 3.5

I can't install .NET Framework 3.5 no matter what I do. I tried downloading it and in the midway get the error 0x800f0906. I tried installing through DISM but that didn't work either. It always stops at 65.8 %.

Can somebody tell me how to fix it? It's really driving me nuts.

It's in "add or remove windows features" - You have to be careful you don't have any "Legacy" dot net, it would be left over from an upgrade. I still haven't figured out how to get rid of it.

I did that but...it asks for the .net 3.5 installation requirement again to install the downloaded file. So its just super boring.
