Adding Multilanguage Support

After you installed the necessary language packs you will have the option to enable the multilingual user interface (MUI) on a per site basis using site settings (this is also possible using the SharePoint Object Model – using SPWeb.AddSupportedUICulture).

I am following this instructions:

The working instructions are down below this one is just for reference of my mistake in using Beta Language Packs.
- http://jopx.blogspot.com/2010/01/multilingual-user-interface-mui-in.html

- While I am downloading I will mak a snaphsot of my VM in case somtehing goes wrong
- Dowloaded language pack Spanish
- Language Setting shows in Site Setting :-)
- Changed Site language to spanish and ERROR !

End of mistake

Now read http://technet.microsoft.com/en-us/library/ff627856.aspx to understand that only interface element are translated not the content :-)

Multilangual content management and multilanguage menu are not implemented by MUI you will need your hown workflow to handle menu and multilingual content management.
