I have no clue, really.
However, I found a cross-reference for Languages here -
Please note that the one you specified is an UNOFFICIAL one! That means MS did NOT issue it but it was "assembled" by an MSFN (probably) member!
Using "web.archive.org" any MS Bulletin (e.g. http://www.microsoft...n/MS05-002.mspx) may be redirected to your language thusly -
See the inserted Language?
Any Download -may- have the following changed (the appended language) e.g. -
Any KB article -may be changed thusly -
anywhere "en-us" is in the website address just change to "ja-ja"
In that particular case (Q891711/KB891711), it specifically states that the Update would have to come from MS Updates. In other words, those listed as downloadable (if they still exist) were obtained (probably) by members and assembled accordingly.
Sorry, but that's the best it gets. You're WAY too late to get any help, since many/most downloads have been obliterated from the MS website, as is many/most articles/downloads for anything LESS than Windows Vista. You see, Microsoft is "cleaning house" right now.
HTH and, again, Sorry
