Low security enables macros without thought. The security level is set by
each Word user for their own installation. It is not something that your
template controls. If they have security set to high, macros will be
disabled without thought. If they have security set to medium, the user will
be queried as to whether or not to enable your macros.

If your template is placed in the user or workgroup templates folder and the
user has "trust installed templates and Add-Ins" enabled, your macros will
run. For more on the different kinds of templates, tabs on the file new
dialog, and locations of templates folders see
