The Professional edition of this program is full-featured - all of the program's capabilities are available - and is priced at US$195

The Student edition is free and is designed for the student, hobbyist or light industrial user. It is limited to seven "stages" of components. This has been done to encourage purchasing the key to unlock the program to the Professional level. Otherwise all of the program's capabilities are fully operational.

Elsie is supplied as self-extracting 32-bit Windows® installation file of about 5MB.

Updates are free; just come to this page, download and then install the Student edition again. The Student edition needs no key. The key you can purchase will unlock the free Student edition up to the Professional level, even after downloading and installing the latest version.

The current version is 2.23 - get it here:
