  1. I know this article is old but under Solution 3, your command contains too many spaces. So when copying and pasting, it gives an error when entered in the Command Prompt. There should be no spaces between the “/” and the operation. For instance, instead of “/ Online” it should be /Online and so forth with the next two operations.
