Has anyone seen or solved this error message:
Could not load type 'Microsoft.AnalysisServices.SPAddin.DataRefresh.ViewDataRefreshHistory'?
it occurs when I click Manage PowerPivot Data Refresh from a document library, specifically on a spreadsheet.
If I reboot sharepoint, the problem goes away, but eventually returns - usually the next day. perhaps some errant process is interfering with sharepoint, but I certainly at a loss to what it might be.
uls is not very helpful.
