Install Japanese in windows XP Professional without CD installer. I try it with Japanese for Office XP, but I have problem.

I want to install Japanese language in my windows XP Professional. But, I don't have CD Installer. So, I tried to search how to install it without CD installer. I'm just got this way for Office XP until now.
The first, I installed Japanese Language Pack http://www.microsoft.com/en-us/download/details.aspx?id=8289 And it have been successful. Then I restarted my computer, but it still cannot read Japanese letters.
And I installed Global IME (Japanese) http://www.microsoft.com/en-us/download/details.aspx?id=22917
While it was installing, the error message appeared. And it said this setup require Office XP. I feel strange because the page said that Japanese Language Pack required Office XP, not Global IME(Japanese) said that. But, when I was installing Japanese Language Pack, there was not problem with Office XP. So, please help me. are there another way to install it? Thanks in advance.
