Installation Failure 0x80073701 KB5029250

Copper Contributor

I have a new Lenovo ST50 and newly installed Windows Server 2022 standard, brand new has not left my workbench. Windows Update keeps failing, started with:

 

Installation Failure: Windows failed to install the following update with error 0x80073701: 2023-08 Cumulative Update for Microsoft server operating system version 21H2 for x64-based Systems (KB5029250).

 

Now its changed to:

 

Installation Failure: Windows failed to install the following update with error 0x80073701: 2023-07 Cumulative Update for Microsoft server operating system version 21H2 for x64-based Systems (KB5028171).

 

How do I fix this?  I need to install onsite shortly and can't have these problems.

 

I am also seeing the same error regarding a language pack.  I am in Canada and the only language we need installed is English.  I'm not sure why cs-CZ is installed, but when I try to remove it, it also fails.  I adding this info because the error # is the same as the windows update.

Not off to a good start. 0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. You can also try a repair install by running setup.exe from the root of the install.

I wouldn't hold much hope for this or spend any time trying to fix, time would be better spent standing up a new one, patch it fully and migrate the roles or applications over to it.
