[SOLVED] Windows Server 2019 Standard Edition - monthly update gets 0x80073712 - missing clean mscordacwks.dll

[LarryK]

TL;DR - Need to obtain clean (appropriate) version of mscordacwks.dll to fix Windows Server 2019

Current issue: Package KB5012647 failed to be changed to the Installed state. Status: 0x80073712.

Problem back-story:

RMM reported errors on Dell BOSS C drive RAID.
Dell Support says to delete RAID and rebuild then reinstall OS and applications.
Datto has safe system snapshots taken before errors occurred.
Run Datto BMR utility to newly built RAID.
Now, we can no longer run Windows Updates without getting 0x80073712.

Ran SFC /SCANNOW
Ran DISM /Online /Cleanup-Image /RestoreHealth - first with Win Server 2019 ISO and then without.

Only one remaining file presents as bad.

Attached are the most recent CBS and DISM logs.

Anything else you need, please let me know.

Hi,

This file is missing or corrupt, I'm going to search for a good copy of it.

Acknowledged - also wondering if simply running the .Net repair utility will do it?

 

[LarryK]

The answer to my question is: Yes, the .Net repair utility does fix this error:



I appreciate your diligence with these two cases.
