Are you running vista?

No, I'm on XP serv. pac 2

If you run Vista:

- enabled uac:

allow all programs to run and you should get 2 updaters, 1 will work for 1 update, repeat untill you have completely updated

- disabled uac:

enable uac

If you run XP:

keep trying, maybe reinstall KWR or change the version info back, so it reupdates everything.
