[SOLVED] Error 0x80073701 on two Windows Server 2019

[prolannic]

We have two Windows Server 2019 that receives the following Error when installing .net Framework CU (KB5046540): 0x80073701
We already ran dism /online /cleanup-image /scanhealth but no corruptions were found. Also we've resetted Windows Update and recreated SoftwareDistribution. SFC /scannow also found no errors.
On one of these servers we tried an inplace upgrade which failed aswell

Attached you find the CBS Logs and the ComponentsScanner Logs.

Hi everybody

I tried some stuff from different threads and found these two errors on all three servers that have this issue:

2025-01-06 20:48:31, Info                  CBS    Failed to pin deployment while resolving Update: Package_8_for_KB5039879~31bf3856ad364e35~amd64~~10.0.4101.4.5039879-195_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
2025-01-06 20:48:31, Info                  CBS    Failed to bulk stage deployment manifest and pin deployment for package:Package_12_for_KB5046268~31bf3856ad364e35~amd64~~10.0.4121.1 [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]

I then tried to expand / add-package with DISM for KB5039879 (successfull) and KB5046268 (not successfull, error 0x80073701) like mentioned in this post. But after a reboot, I'm getting the two errors again in CBS log. I also tried

DISM /Online /Cleanup-image /RestoreHealth

after the add package without success.

I've now run

wusa /uninstall /KB:5039879

which uninstalled the update successfully.

After a reboot I was finally able to install the .net CU.

Hope this helps someone.
