How do I modify the user interface language in SSMS?
To change the language in Microsoft SQL Server Management Studio 2014:
> Tools > Options... > Environment > International Settings > Language
This might help:
Install SQL Server 2008 R2 on a Multilingual User Interface (MUI) system on MSDN by Peter Saddow
From that link:
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 enabled for the same language.
You can also reinstall it using a different language version of SQL Server.
