@econs Try this - https://www.computerbase.de/downloads/systemtools/all-in-one-runtimes/ , should install all the runtimes for you and if you still get that error, no clue mate. Sorry.
@AnTVortex no idea, that error means the update service is not running.. open the start menu and search for services -> open it -> look for "Windows Update" -> right click -> start.
