Some updates were not installed, get the error code 646

Some updates for windows vista, you receive the error code 646 were not installed and I tried to update manually by using registry files and still isn't updated do not know what is the problem, but when trying to install update, say, it's something on a restore point for the update

Hi Lori,

-What are the updates that fail to install?

I suggest you try the steps in the following Microsoft Article.

You receive the error code: 0 x 80070646, error code: 646 or error code: 1606 when using Windows Update or Microsoft Update
