SQL Server 2008 R2 SP1 Installation Error 0x84B20001

With SharePoint 2010 SP1 and SQL Server 2008 R2 (CU6 at the time) with Database Engine, SQLServer Reporting Services, and PowerPivot, I ran into the following error:


Clicking OK would exit the installation process. Modifying the following value fixed the issue: HKLM\Software\Microsoft\Microsoft SQL Server\100\ConfigurationState and change Analysis_Server_SPI to “1” to fix the “[Analysis_Server_SPI,]” error. To fix the PowerPivot error, modify HKLM\Software\Microsoft\Microsoft SQL Server\MSAS10_50.POWERPIVOT\ConfigurationState and change “Analysis_Server_Full” to “1”. In my case, the data was “2”.
