INSTALLING
You can perform a Notes multi-user installation with the Multilingual User Interface (MUI) pack.
For a multi-user install, the Notes® user interface files are installed in the following directory:
C:\Program Files\HCL\Notes\MUI\language-iso (*)
Note: The language-iso (*) represents a language identifier. Language identifiers are Arabic (ar), Brazilian Portuguese (pt-BR), Catalan (ca), Czech (cs), Danish (da), Dutch (nl), Finnish (fi), French (fr), German (de), Greek (el), Hebrew (he), Hungarian (hu), IB Portuguese (pt-PT), IB Portuguese (pt-PT), Italian (it), Japanese (ja), Korean (ko), Norwegian (no), Polish (pl), Russian (ru), Simplified Chinese (zh-CN), Slovakian (sk), Slovenian (sl), Spanish (es), Swedish (sv), Thai (th), Traditional Chinese (zh-TW), Turkish (tr).
When a user starts the Notes client for the first time, the user interface and database language are determined by the user's operating system locale setting. If the locale language is not found in the directory\mui, the English user interface is used and English databases are created to set up the Notes client. If the locale language files of the Notes client have not been installed, the user interface language of the Notes setup and local databases defaults to English.
For example, in a multi-user installation, if you add French and Japanese files with a MUI pack, the user interface files are installed in individual directories such as these:
C:\Program Files\HCL\Notes\MUI\fr
C:\Program Files\HCL\Notes\MUI\ja
