From this page, you could previously download and install the GEMPACK Windows programs WinGEM, TABmate, ViewHAR, ViewSOL, AnalyseGE and RunGEM. One reason to do this might be: you do not have the full GEMPACK system, but would like to use viewing programs ViewHAR and ViewSOL to examine data [HAR] and solution files [SL4] that you have obtained.
In such cases we now recommend that you download and install the trial verson of GEMPACK. After the trial licence expires, you will no longer be able to create or edit new models. However, most GEMPACK Windows programs will continue to work, as they do not require a GEMPACK licence for much of their functionality.
