Help with a game install

I download the game tayutama - kiss on my deity, but here it is not given how to install it. I expect anyone's help if anyone knows. Thanks.

Something more info would not be bad...

Is it a Japanese game?

If so, your computer must have the Japanese locale, the easiest way to do this is to install the Apploace. From google find more detailed information.

I got a locale app that worked, thank you very much :)
