Assume that you enable PowerPivot for SharePoint in Microsoft SharePoint Server 2013. After you remove PowerPivot for SharePoint from the SharePoint farm by using the SharePoint Configuration Wizard, the PowerPivot gallery is still displayed on SharePoint sites. However, when you try to access the gallery, you receive the following error message:
Could not load type 'Microsoft.AnalysisServices.SPAddin.ReportGallery.ReportGalleryView'
To recover documents from the PowerPivot gallery, access the PowerPivot gallery by using Explorer View.
