I think the bundled Solutions Disk should have a few languages available, I'm not exactly sure. If it does, then choose the desired language prior to install.
AFAIK all official web updates require that you have the original software installed, meaning you MUST have the original Solutions Disk handy.
I have checked P2P networks and undortunately can only find Solutions Disks (ISO images) of older versions.
Maybe the best solution is to contact Canon HK regarding this issue.
