Set-up

GREAT-ER comes with its own set-up program, specifically designed for the installation of the complete modelling system. It can be found in the basic directory of the GREAT-ER CD-ROM. It is recommended to exit all other running applications while installing GREAT-ER on your computer.

Installation steps (some terms are language dependent and may be different on your WINDOWS NT 4.0 version:

1.
Insert the GREAT-ER CD-ROM into your CD-ROM drive. Run the setup program by selecting "Execute" from the WINDOWS NT 4.0 "Start Menu". Type e.g.
D:\setup.exe
and click the "OK" button. Please note that D has to be replaced by the drive letter of your CD-ROM drive.

2.
The first dialog appears, showing you the licence text of GREAT-ER. Please ensure you have carefully read and understood all terms of the licence agreement. If you agree to the licence agreement, proceed with the installation by clicking the "Accept" button. If not, select "Cancel". The installation will then be aborted and GREAT-ER will not be installed on your system.

Within the following dialogs you can return to a previous dialog to modify settings by clicking the "Back" button.

3.
Select the type of installation either full installation or CD-based installation. It is recommended to proceed with the full installation. The CD-based installation should only be chosen for evaluation purposes: The required disk space is reduced to the amount of data resulting from simulation runs; all scripts, programs and additional data are loaded for a GREAT-ER application from the CD-ROM. This means the CD-ROM needs to be inserted in your CD-ROM drive while working with GREAT-ER. On the other hand, it is not possible to add news substances to the systems data base or to include further catchments or additional geo-referenced data.

4.
If you have selected the full installation, the following dialog will enable you to specify the directory in which to install GREAT-ER. A directory can be specified by typing in the path directly or by browsing through the directory tree. If you type in a nonexisting directory, the setup will create it for you. Please note that only the last directory in a path can be created, new multi-stage directories are not possible. (E.g. if C:\programs is an existing path, greater and therefore C:\programs\greater would be a possible directory for the GREAT-ER installation. C:\programs\models\greater would not be allowed if models is not an existing directory. It has to be created manually using the Windows NT options before proceed with the installation.)

5.
For both types of installation a directory to store the scenarios has to be specified (see below). Restrictions are the same as for the GREAT-ER installation directory.

6.
A final dialog enables you to review your settings. Click back to modify your settings or complete the installation.

7.
The set-up evaluates the source files and starts to install GREAT-ER. Please note that on some systems the progress bar reporting the process of installation will not function properly.

It is recommended to restart the computer after installation to ensure correct recognition of new system settings.

8.
For a more practical start, you can create a link to the GREAT-ER program in any of the start menus program groups or on the desktop.

The link target should be as follows:

<ArcView path>\arcview.exe %GHOME%\great-er.apr
where <ArcView path> has to be replaced by the path to your ARCVIEW installation (e.g. C:\ESRI\AV_GIS30\ARCVIEW\BIN32).
