Problem: Customer was experiencing the error below when trying to view a PowerPivot workbook in their SharePoint site. This was only occurring in their production farm.
I also found this error in the logs:
Troubleshooting:
- verified they had the SQL Server analysis service instance enabled on the PowerPivot/SharePoint server (problem still occurred)
- verified that their Excel Services account has the below permissions on the SQL Server Analysis Server (problem still occurred)

Resolution
When running the following commands to see the build level of SSAS, we found the problem:
$server = "serverInstancePowerPivot"
$aso = New-Object Microsoft.AnalysisServices.Server
$aso.Connect($server)
Write-Host "The SSAS server version is: "$aso.Version
We saw that the SSAS version is different in CERT and PROD and it is working in CERT not in PROD. The PowerPivot Add-in version is 11.1.3437 on the App servers in both CERT and PROD. Had to update SSAS on PROD to 11.0.3437
