Are you asking whether or not the installation can be performed in a language other than English?
Or, are you asking whether or not you can change the language in which the operating system is displayed after the operating system is installed?
In either case, the answer is yes. If you are referring to changing the language in which the installation program is displayed, the first screen of the installation gives the user the option of choosing a different language to use for the installation process.
If you are seeking to change the default operating system language after you have already installed Vista, just go to Control Panel -> Regional and Language Options. Once you are in the Regional and Language Options control panel, choose the "Keyboards and Languages" tab. Under the "Display Languages" subsection, click "Install/uninstall languages...".
Hope that helps.
