WU_E_UNINSTALL_NOT_ALLOWED

WU_E_UNINSTALL_NOT_ALLOWED means the requested uninstall is not permitted in the current source context. The Windows Update Agent does not treat every update as generically removable by every caller.

What to check

Verify the update source and whether the package was deployed through a workflow that supports uninstall.
Confirm the update itself is uninstallable; many servicing packages are permanent or superseded rather than removable.
Use the supported servicing or management path for the package instead of trying to force a WUA uninstall request.
