How to add other languages in Microsoft Word 2007?

Hi techyv,
Standard chinese font free download is not working. I tried to install the font for my Microsoft word 2007 application just for fun. I want to try another language and see how cool it looks like. But it seems like there are some compatibility issues. Can you share with me some points to be considered? I am using windows 7 operating system.
Hoping for your help and kind consideration.
