Normally you just click on the usual buttons(trial and error)for installing and get it done.
If you want to play it in English, get the patch.
Else figure out which language it is in, install that language via Windows Vista Installation Disc(most probably in japanese),

Life is but a River.
A continuous flow,relentless till it reaches its destination.
Rocks,rapids,falls hinder not the flow of the strong.
It has its ups,and its downs.
And in the end,peacefully.......
It dissipates into to vast Ocean.
