[SOLVED] Windows Server 2016 - Cannot install Windows Defender Role - Error 0x80073701 The referenced assembly could not be found.

PWischnewski · Jun 18, 2021

Hi,

I cannot install the Windows Defender role on the server in question. Windows updates run without errors. But there were installation errors for some Cumulative Updates back in 2019 and 2020 (KB4537806, KB4512517).
SFC / Scannow does not find any errors. SFCFix does not find any errors, but aborts the DISM scan with error 14. DISM / Restorehealth aborts with error 14 not enough memory available. CBS Manifest Corruptions can be found in the CBS.log.

Thank you for your help!

Hi SleepyDude,

many thanks for your response.

I followed your instructions. Dism /Online /Cleanup-Image /ScanHealth runs without errors. I restarted the server. But still no luck with the Windows Defender Role (same error).

Hi,

Are there any language pack installed on the server?

PWischnewski · Jul 6, 2021

Yes, it is a multilanguage preinstallation.

SleepyDude · Jul 6, 2021

Please remove all the language packs except English.

PWischnewski · Jul 6, 2021

German is the standard language of the server. I wouldn't want to uninstall this.

When uninstalling the other languages, I get error messages.

SleepyDude · Jul 6, 2021

Hi,

I understand but to work on this kind of problem the system must be using the base language that is English then after successfully install the updates the language packs can be installed again.

The log show the same problem with two updates lets try to reinstall them and see if that helps.

Install Update using Dism

Good news...problem solved! I just installed Windows Defender without errors. Thank you, SleepyDude.

That is great

This kind of corruption can be hard to fix, I'm glad it was a more simple case.
