When Elsie is run, it normally operates in the
Student mode. If it finds the purchased key, it
automatically upgrades itself up to the full
Professional mode with no effort on the part of
the user.
By purchasing the key - priced at US$195 - the program
will automatically operate in the Professional
mode.
The keyless Student mode of operation is designed for
the student, hobbyist or light industrial user. It is
limited to seven "stages" (dipoles) of components. This
has been done to encourage purchasing the key to unlock
the program up to the Professional level. Otherwise
the two modes of operation are identical.
Elsie is supplied as self-extracting 32-bit
Windows® installation file of about 6MB.
Updates are free; just come to this page, download and
then run the installation file. It will uninstall the
old version and then install the new version. The Student
edition needs no key. The key you purchase will unlock
the free Student edition up to the Professional edition,
even after installing a new version.
The current version of Elsie is 2.55 - get it here:
