Ive been struggling with .NET framework 3.5 installation for a few weeks now. There is a couple of programs that seems to need it, and I just cant install the framework.

Ive tried enabling it from the programs and features menu. It seems to copy the files to %windir%\Microsoft.NET\Framework\v3.5 directory, but after that it says:
Windows couldnt complete the request changes. Windows requires a reboot to return the system to its original state.

Ive tried this also:
DISM /online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs

Deployment Image Servicing and Management tool
Version: 10.0.10240.16384

Image Version: 10.0.10240.16384

Enabling feature(s)

Error: 0x800f0922

DISM failed. No operation was performed.
For more information, review the log file.

Thats my USB stick that I used to install the win10 pro. I have also tried the dism /scanhealth and repairhealth etc commands. Also tried that lodctr /r but it didnt help and tried also the ccleaner.

I can post some CBS logs to pastebin in a while if someone wants to take a look..
edit. Here are the lines with keyword error: 2015-09-28 11:54:33, Info CBS Appl: Package: Microsoft-Windo - Pastebin.com

Wondering what these lines are:
