I installed the MOSS 2007 language packs (or so I thought), but couldn't understand why the 'Select a language' drop down did not appear in the Site creation page.
I followed the instructions here;
I downloaded the language pack from the following URL;
Then I discovered that you have to select the language you want from the drop down and then click change. Then you have to download the language pack from that page. Interesting given that I don't read or speak any of the other languages.
Then I installed those language packs (after extracting them using WINRAR).
Even the installation is in that language :)
