Download the Limited Executable-Image Version of GEMPACK Release 10

From this page you can download the Limited Executable-Image Version of GEMPACK Release 10.0-001 (April 2009) of GEMPACK, for PCs running Windows XP or later. 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.

Free Trial

This free download comes with a temporary licence lasting 3 months from the download date -- long enough to experiment or to complete a class assignment. After 3 months the licence will expire -- to go on using the software, you would need to purchase a licence.

Download and installation

If you are going to attend a laptop-based training course please follow the simplified "QuickInst" instructions available here. Otherwise, please follow these steps:

First, download, print out, and read the install instruction document GPD-7.
Second, download the install program (it will have a name like "gpei-10.0-001-install.exe"). Save this file, but do not run it yet.
Third, follow the instructions in the GPD-7 install document that you downloaded.

Getting started

The download includes PDF versions of the main GEMPACK manuals: documents GPD-1 to GPD-9. In particular, document GPD-1 contains an introduction to GEMPACK and document GPD-8 contains detailed hands-on instructions to get you started carrying out simulations with several models. We encourage you to start with these.

If you are an experienced GAMS user, you can take advantage of your GAMS skills to get a head start with GEMPACK.
