PowerPivot Error Message

Question

PowerPivot was working fine for me last night. This morning, when I open my workbook, PowerPivot simply won't launch. The button is not grayed out, but when I click it, nothing happens.

Clicking on any of my PivotCharts produces a field list like it should, but it tells me that I should "Refresh" my data. I hit refresh, and get the error message:

Embedded Analysis Services Engine: Could not load embedded PowerPivot Data. 

Every once in a while after this error message, I get another telling me that my Powerpivot data is corrupt, and I have the option to do nothing or attempt to recover it. When I attempt to recover it, it tells me that the data recovery has been successful, but all of my charts and pivottables are now wiped clean of data, and Powerpivot still will not launch.

I've tried Googling this and looking at the solutions online. I'm already an administrator on my computer. I've tried rebooting and re-installing PowerPivot. Any help would be greatly appreciated.

Answer 1

You need to follow the instructions at the fowllowing website to turn off the UAC in Windows 7. That will allow PowerPivot to work. The link is http://technet.microsoft.com/en-us/library/cc731416(WS.10).aspx
