office 2007 Multi Language Pack

I have purchased license and CD kit for office 2007 english and cd kit for english office multi language pack 2007. I want to install in Vista operating system korean version. After installation, the office program like Word, Excel language are still in use for 37 countries language along with korean language. So, why is this office version still in english menu? Am I suppose to purchase the office 2007 and multi language pack for korean language as well? Thanks

Even I am facing the same problem. I have just upgraded my Vista Businedd to Enterprise version, which is required to support multi-language pack but still it wont work. The user interface for my Office suite in English and I want it to be in Chinese?
