From this page you can download the Limited Executable-Image Version of GEMPACK Release 11.4 (January 2016) of GEMPACK, for PCs running Windows. It includes all the main GEMPACK programs and can carry out a full range of modelling tasks. There is however a model size limitation: this version can only solve medium-sized models. All simulations are carried out with the GEMPACK program GEMSIM -- no Fortran compiler is required.
This free download comes with a temporary licence lasting 6 months from the download date -- long enough to experiment or to complete a class assignment. After 6 months the licence will expire -- to go on creating or editing CGE models, you would need to purchase a licence. However, viewing programs such as ViewHAR and ViewSOL will continue to work, as they do not require a GEMPACK licence for much of their functionality.
If you are going to attend a laptop-based training course please follow the simplified "QuickInst" instructions available here. Otherwise, please follow these steps:
The download includes the most recent GEMPACK manual (in both HTM and PDF formats). Chapter 1 of the manual directs new users to introductory material, and experienced users to a list of new features.
If you are an experienced GAMS user, you can take advantage of your GAMS skills to get a head start with GEMPACK.
