What I need for work with PowerPivot?

Hi carlosam1409,

Based on your description, you said you got the error message is PowerPivot is unable to load the Data Model. If this error message is the whole error message?

And you said when you opened the manage window icon and get this error. In this circumstance, the reason for this error was by design and caused by modified user permissions. This error does not happen for an Administrator user.

With this kind of issue please read this article for more information:
