You must be an administrator to open Internet Explorer on this desktop.

You receive this error message even after you log on by using an account that is a member of the Administrators group.

Note This problem does not occur in earlier versions of Windows. These versions include Microsoft Windows XP and Microsoft Windows Server 2003.


This problem occurs if you try to start Internet Explorer 7 on a desktop that is not the default desktop. A program may switch the user to a desktop that is not the default desktop.
