Whenever I try to install I get this message. I'm running as admin and in Japanese Mode. I have no idea what this error means, or how to fix it. Is this game compatible with x64 bit systems? I have Vista Basic 64 bit.
Also, I have installed the included Direct X and definitely met the system requirements.
I have tried to run the installer in compatibility mode as well with no effect.

I finally got it to work! All I had to do was install it manually (by copying the files from the data folder over). Anyways, I'm very sorry for an inconvenience this may have caused. It was possible to get the game to work, though the installer still doesn't want to work for some reason.
