You are here: Getting Started > Using ProModel > Creating Run-Time Models
One of the most powerful features in ProModel is the ability to create models that may be run by others who do not own the full software. PROMODEL allows you to install the software on any machine to run a model. However, without the security key, the user has limited ability to build or make changes to a model.
You may wish to develop run-time models to allow the user to perform "what-if" analyses with the models. PROMODEL encourages you to develop demonstration models, and allows you to distribute them freely. These models can be run by installing ProModel from the CD-Rom onto a computer without a security key.
