Question about Outlook Express

Greetings.

In another thread titled "Language Package, spelling check for Windows Mail 6.0", in response to the spellchecker problem of the Original Poster somebody suggested using Windows Live Mail because it supports more languages (37, it said, though it was a two years old thread). Around the Internet, I've seen that many people have trouble finding the options for changing languages and tutorials have been provided to show how to do that. However, in all those tutorials everybody seems to have dozens of languages in the list in the options panel for spellcheck, with those installed marked as such and those not installed but listed marked as "available".

My question is, why don't I have those options? I have used WLM 2009 under XP and 2011 under Seven, both English and Italian (my native language), and the first only comes with pre-installed English languages (variations for US, UK, Canada and Australia), and the second comes with the same plus Italian. But if I want to install Spanish or German, say, there simply is no option. The list is limited to those I've mentioned, the buttons to its side are all dimmed, the only choice I have is which one to set as the default. Why is that so? Why isn't there a way to install all those other languages? Or is this feature limited to the 2011 version only? And why would that be, since it's only available from Vista upwards and tons of people, businesses and administrations are still stuck with XP?

I've seen around a few tutorials to manually install languages by moving some files and editing some ini files, but first I'd need the actual files containing the languages I want to use, and I assume these should be available somehow through the MS Download site. Or am I supposed to download each localized version of the WLEssentials, pick it apart and extract the files on my own? Isn't there a more straightforward option?

Thanks in advance for any input on the subject, best regards.
