Jim bought Microsoft Office 365 for three of his computers, and he's having trouble with licensing on one of his computers. Leo says he'll have to be logged in or it'll give him that pop-up. But it also sounds like Microsoft's copy protection is running amuck.
Leo advises logging out and logging back in. He should also try uninstalling and reinstalling Office. If that doesn't work, then it's likely that running as a limited user is causing the issue. He'll need to right click the icon and then select "run as administrator." He should just do that one time and it'll save the information and he won't have to do it again. But when he runs as a limited user, the program can't save the login information.
