International Character Toolbar for Multiple Profiles

I work in a university library. I wish to implement the International
Character Toolbar on all of our computers for the foreign language students.
However, it appears to be installed on a per-user basis. Our group policies
disable installations, we regularly delete all profiles on a computer, and
all attempts to access the toolbar from another account have failed. I have
tried installing under a profile and copying it to the default. This will
show the toolbar, but will not access the individual characters. I have
tried adding the toolbar to the current template with the same results as
above. Lastly, I have tried using the "COM Add-ins" command suggested by
another user to link the toolbar to the correct .dll. When I do this,
nothing happens.

Is there any way to install the International Character Toolbar once and
make it availble to all users on the computer?

Thanks,
