Another bit of an update to complete the info in the forum:
In order to make the multilanguage, the msi takes the property "user locale"
that
can be retrieved through the function GetUserDefaultLCID.
In a simple C++ console app:

#include "stdafx.h"
#include <iostream>
#include <windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
     LANGID userLocale = GetUserDefaultLCID();
     std::cout << "User locale = " << userLocale << std::endl;
     system("pause");
     return 0;
}

In Windows 7, this does not change when changing the so called display
language, but when changing the language format! (check
http://www.sevenforums.com/tutorials/3527-format-regional-language-change.html
to see where do I mean).

That's it. Changing that my multilanguage msi "works" (yet it does not seem
anymore as a robust/viable solution)

Francisco
