I cannot see thumbnails when I publish a PowerPivot Workbook
I just have the generic icon. There are no thumbnails. Any idea why?
I saw one post that said navigate to:
Site Actions - Site Settings - Site Collection Administration - Site Collection Features - PowerPivot Feature Integration for Site Collections - Activate.
My problem is that I do not see Site Collection Administration when I navigate Site Actions - Site Settings, from the PowerPivot Gallery page of SharePoint.
