I'm running Windows 7 Professional and I'm trying to play Another Bound Neo, a Metroid Prime style game.
It's dōjin soft (Japanese independent game). Normally that isn't a problem, but whenever I launch this game it pops up an error that looks like this:

I'm not sure but I think it might want some sort of Japanese language support installed. A forum post affirmed this suspicion.
I did a quick look around Google, but all that turned up was that Windows 7 Enterprise and Ultimate had patches to add language support.
Am I out of luck here?
