I am setting up a SP 2013 (Enterprise) install, and created a PowerPivot Site Site Collection. Everything seems to be working - I upload one Excel file to the PowerPivot Gallery, and that is fine. It renders the display images correctly. But then if I try to open the Excel file, I get the error:
No Items to Show We can't open this workbook. It's set to show only certain named items, but they aren't in the workbook. You might want to contact the author for more information.
I tried to "Open & Repair" the .xlsx file in Excel 2013 on my desktop, and then re-upload, but that did not fix things. I have no problem with other Excel files I've tried. Any suggestions here?
