Install a display language
You can change the language Windows uses to display text in wizards, dialog boxes, menus, and other items in the user interface. Some display languages are installed by default; others require you to install additional language files.
There are two types of language files:
Windows Vista Language Interface Packs (LIPs). Windows Vista LIPs provide a translated version of the most widely used areas of the user interface. LIPs are freely available to download. For more information, including a list of languages available, go to the Microsoft Local Language Program
Windows Vista language packs. Windows Vista language packs provide a translated version of most of the user interface. Language packs require a license to be used and are available only in Windows Vista Ultimate and Windows Vista Enterprise. If you are using Windows Vista Enterprise, contact your system administrator for information about installing additional languages.
Before you can install a display language, you need access to the language files. These files can be on your computer, on a computer on your network, or on your Windows DVD; or they can be downloaded from the web. For more information about the differences between language packs and Language Interface Packs, and how to get them, see How do I get additional language files?
To install a Language Interface Pack (LIP), double-click the file to open the setup program. To install a language pack, follow these steps:
Open Regional and Language Options by clicking the Start button , clicking Control Panel, clicking Clock, Language, and Region, and then clicking Regional and Language Options.
Click the Keyboards and Languages tab.
Under Display Language, click Install/uninstall languages, and then follow the steps.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
After you install a display language, you need to set your computer to use that language. For more information, see Change the display language.
