windows 8.1 - Repair file detected as corrupted by System File Checker

I ran the sfc /scannow today on the system and it returned the following:

Windows Resource Protection found corrupt files but was unable to fix
some of them. Details are included in the CBS.Log
%WinDir%\Logs\CBS\CBS.log.

The log contained the following info about corrupted file:

Next I ran DISM /Online /Cleanup-Image /RestoreHealth which returned:

C:\Windows\system32>DISM /Online /Cleanup-Image /RestoreHealth

Error: 2

The system cannot find the file specified.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

Does anyone have any idea about Dism.psm1 file and how to repair this?

Answer

The file Dism.psm1 from the package Microsoft-Windows-Client-Features-Package-AutoMerged-base is corrupted.

I've extracted the package into a CAB. Download it, extract the CAB and point to it as source in the DISM command

DISM /Online /Cleanup-Image /RestoreHealth /source:C:\Microsoft-Windows-Client-Features-Package-AutoMerged-base~31bf3856ad364e35~amd64~~6.3.9600.16384
