I had just installed SQL 2008 R2 Analysis Services, Then I rebooted to install SQL Reporting services, all of the sudden i received this error “The ENU localization is not supported by this SQL Server media.”
Copy %InstallMedia%\resources\1033\setup.rll to C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\Resources\1033 * Overwrite the file located here. *
P.S. Know Idea on the Support from MS on this fix. So do this at your own risk.
