The software can be supplied on CD or downloaded from here. After installation it can be run either as a 30 day trial or, at any time after that, as a permanently licenced installation using an activation code that is supplied when the software is purchased.
The basic configuration for Dietplan7 Professional is a single-user licence, that can be used by one person at a time, and the software has administration facilities whereby different individual user profiles can be created so each person can work independently. Dietplan with a single-user licence can be installed either on a stand-alone computer or on a network. In the latter case, the program is accessible and can potentially be run from any PC attached to the network - but only from one at any time.
It is also possible to purchase a multi-user or a multi-installation licence. The cost is based on the number of users or installations.
A multi-user licence allows the installation of a single, shared copy of the software on a network and the licence specifies the number of people that can use the program simultaneously or concurrently.
A multi-installation licence permits the software to be installed on the licenced number of different, stand-alone computers, each with a single-user licence.
