I was at a client recently and was trying to add a new SharePoint Server to the farm, and everything went well until I tried to run the SharePoint Products Configuration Wizard. The error was:
Task configdb has failed with an unknown exception Exception: Microsoft.SharePoint.Upgrade.SPUpgradeException: Failed to call GetTypes on assembly Microsoft.AnalysisServices.SPAddin, Version=126.96.36.199, Culture=neutral, PublicKeyToken=89845dcd8080cc91. Could not load file or assembly ‘Microsoft.AnalysisServices.SPClient, Version=188.8.131.52, Culture=neutral, PublicKeyToken=89845dcd8080cc91’ or one of its dependencies. The system cannot find the file specified.
The problem is that the rest of the farm had the PowerPivot enabled, and therefore the PowerPivot Addin is required. Unfortunately, This Add-in is not verified at the begging of the SharePoint Products Configuration Wizard standard check, so that is why you get to this error. A recommended best practice is to install spPowerPivot.msi on all servers in the SharePoint farm for configuration consistency, including application servers and web-front end servers. The installer package includes the Analysis Services data providers as well as the PowerPivot for SharePoint 2013 configuration tool. To fix the problem, simply download the installer file from Microsoft Download Center: Microsoft® SQL Server® 2014 PowerPivot for Microsoft SharePoint®, run it on your server and then re-run the SharePoint Products Configuration Wizard. Everything should work perfectly!
