I understand.  
But this is the path to the font cache, not the path to the library executable.

You really do want a shared path for system fonts.
Otherwise all programs that use the fonts suffer from this same problem.
Sharing a font cache will benefit all of the them.

Doesn't windows have some way of setting this once for the user,
rather than many times for each program that runs?
