Another problem is for those (like me) who choose the Update Site installation instead of the All-in-One.
When I follow the suggestion above, MyEclipse > Manage MyEclipse plugins, it says
Dashboard Not Available – The MyEclipse Dashboard is only available from a full version of MyEclipse.
How should I update to 7.1.1 ?
And why would MyEclipse not use the standard eclipse update mechanism ?
