> Originally silent install installed all 100+ languages and it made the
> installation slow. For 3.5.4 it was solved by running the language
> pre-selection custom action not only during normal install, but during
> silent install, too. Unfortunately it caused another problem, because
> now users of silent install do not have the opportunity to select UI
> languages, they always get what the SelectLanguage custom action
> selects for them, i.e. the languages of the operating system.
>
> Here comes the solution. If the UI_LANGS property is set, the language
> guessing heuristic is switched off, and user can define explicitely,
> what languages should be installed.
>
> E.g.:
> msiexec /i LibO_...._.msi UI_LANGS=en_US,de,fr,hu
> It will install English (US), German, French, and Hungarian. There are
> still some minor issues with language selection, because for example
> pt_BR also selects pt implicitely, but this is the same what we have
> with automatic language selection.
>
> When the user tries to fool the installer by giving invalid language
> codes, installer will fall back to en_US. Also, en_US is not installed
> by default, unlike with the automatic selection. I tried the patch
> with a limited set of languages (10), and it worked well. Please
> review the patch for 3.5 (better to ignore whitespace changes, when
> you view the patch).
