Add language to office 2003 standard editon

Hi All,

Can anyone please advise on how to add a language to the translate in word 2003 standard. My office version only has about four languages and want to add another language so I can change the text from english into the other.

Can anyone please advise on
A) How to do this - download and from where to download additional language support from
B) How to install the package is it just a straight install

I have computers at work that have this facility but I am not sure if the versions are compatible. As these are Office 2003 professional, is there a possiblity that i can copy a file from this version, if so where is the file located?

Any ideas guys?

It maybe proofing tools but I am unsure as I havent tried this before...:confused

Thanks in advance:wave
