The only solution I've found thus far is to copy my db file to a thumb drive, copy it to a 32-bit Windows installation from that, and run the tool from there. Not the most elegant solution, but it works.
EDIT: Forgot to add (not sure if it was already mentioned), if there is no box art for a game and you apply it, it will duplicate the last box-art image that was used for a previous game. This is causing me to have to delete the image file and go search for it on my own, which I guess is a blessing in disguise since it is forcing me to find a box art image for all games.
