I have uploaded a PowerPivot workbook to the PowerPivot Gallery and am now attempting to use it as a data source for PerformancePoint, but I keep received the following error when making the connection in Dashboard Designer: "An error occurred connecting to this data source. Please check the data source for any unsaved changes and click on Test Data Source button to confirm connection to the data source." The file is not open and the Test Data Source button is grayed out. What is the proper URL syntax? I'm not sure if the URL is the problem either. Any help would be appreciated.

Did you add it as a trusted source? –  Mike Nov 13 '12 at 22:19
I'm experiencing the same issue described here. Does anyone have the resolution? I'm hoping the install described at denglishbi.wordpress.com/2012/02/09/… will be useful. I'm not an admin so I cannot install it myself. Before I ask the admins to drop what they are doing and try something are there other ideas? –  user18886 Aug 13 '13 at 14:37
