How do I fix corrupted mscorwks.dll?

Hi guys.

So today I ran the sfc /scannow on cmd and found out there is corrupted file that cant be fixed.

I checked the CBS.log and found this:
"Could not reproject corrupted file [ml:520{260},l:102{51}]"\??\C:\Windows\Microsoft.NET\Framework64\v2.0.50727"\[l:24{12}]"mscorwks.dll"; source file in store is also corrupted 2016-06-26 07:37:22,"

Been referring to this thread but no luck for me:
SFC /SCANNOW Error and System Image Error

What I have done:
-Repair the .NET from control panel
-Try to install hotfix but failed (not applicable)
-Reinstall .NET

What can I do to fix this problem?

Thank you.
