Windows 7 64bit - March Monthly Rollup KB4489878 fails to install with Error code 80073712

Hi,

March Monthly Rollup update (KB4489878) fails to install with error 80073712. If I hide that update, February Monthly Rollup update fails with the same error.

The last successful Monthly Rollup update was January's KB4480970. If I try to uninstall that update, I get an "An error has occurred. Not all of the updates were successfully uninstalled."

Trying to install the .cab manually through DISM fails with Error: 14098. The component store has been corrupted.

SFC Scan doesn't find any errors.

Thank you in advance.
