Well, the bat should do something when run, I have no idea what happened to it. Maybe some antivirus killed it.

As Eclipsed says, it looks like you only have the english patch files. Basically a "patch" is used like this: you first get / install the original japanese visual novel, then you "patch" that installation using what the translation team gave you (in this case by extracting those files into where you installed I/O and agreeing to any overwrites, far as I recall). You'll need to get the Japanese VN somehow.
Eclipsy and Griev (now Keaton, and I still have no idea why he changed names) just merge into one entity in my mind. Aren't you both trolls and have both been on ts3 at some point?
