Windows 10: .Net framework 4 installation error 0x000013EC

-Win 10 pro

-This happened after win 10 version 1803 update.

-Later upgraded to 1809(updated after 1803), no change

-No restore point exists.

-No more windows updates available.

-The system says DotNET is installed when trying to install any available (tried them all) version.

But it is not listed under windows features correctly. The list says "NET Environment" which is a strange entry cant be turned on.

Under registry DotNet 4 is not installed Windows feature seems to be broken.

-All DotNET dependent software has stopped working and give error messages.

-Tried: Run sfc scannow

-Tried: Offline installation from offline folder gives the following message https://prnt.sc/lcb1tw

ALL DISM command have been tried. NetFx3 and 4 installation and restore health. NetFx3 and 4 feature cannot be turned on(enable-feature) (online and from folder)

-I have replaced the .cab files and tried to enable feature after that. Didn't work as before.


-Tried: net user administrator active:yes Also created a new admin user on windows and tried to install DotNET with that user. Same errors.

-I have used win DotNet framework verification tool, Microsoft DotNET Framework Repair Tool, DotNET cleanup tool.

-Also, I can't access group policies http://prntscr.com/lgyzn0

-Installed 4.8 DotNet preview. Installation 100% fine. Still no change. Tried installing other older version http://prntscr.com/llcncy
- Tried in-place upgrade 3 times. Same error.

Also, just to get rid of the people who say "have you made sure the computer is turned on" sort of help, I will mention that Microsoft support failed to help me and gave up. Although they did NOTHING that wasn't mentioned in online guides or forums and I hadn't tried before.
