Install SQL Server 2008 R2 on a Multilingual User Interface (MUI) system

  • Article

Just like SQL Server 2008, you can install SQL Server 2008 R2 on a MUI system. Additional checks have been added to SQL Server 2008 R2 to ensure you don’t install on an unsupported localized or MUI system. Therefore it is important you properly configure your system prior to the installation.

 

Here is the official documentation on the SQL Server language support: https://msdn.microsoft.com/en-us/library/ee210665(SQL.105).aspx.

In summary:

  • English SQL Server is supported on all localized versions of operating systems
  • Localized versions of SQL Server are supported on the same localized operating system or English system with MUI enable for the same language.

Below, I have the instructions on enabling MUI on a Windows 7 system but should be similar for other operating systems.

 

1. Open up “Region and Language” and choose Japanese.

6. Now run the localized version of SQL Server.  If you immediately see a message indicating the language is not supported, ensure the language that you are trying to install matches the MUI language and the setting above are correct.
