Installation Instructions-
Geochem-EZ will work on any computer that is running a Windows XP, Vista or Windows 7 operating system.
It also requires that the computer have Java SE6 update 7 or higher, which is available for download from Sun Microsystems (http://www.sun.com/download/index.jsp).
If you are not sure whether you have the correct version of Java or whether you have Java at all, then visit: http://www.java.com/en/download/help/testvm.xml?ff3 and it will test to see what is installed on your computer.
-------------------------------------------------------
Installing GeoChem-EZ
-------------------------------------------------------
Geochem-EZ is downloaded as a zipped file.
Install GeoChem-EZ by copying the contents of the unzipped file folder
into a directory WHOSE PARENT IS A PARTITION AND IS NAMED WITH FEWER THAN NINE CHARACTERS and contains no special characters. We apologize for this inconvenience, but this is necessary for the old GEO-CHEM-PC executable to run. For example, place the Geochem-EZ files into C:\GeoEZ or D:\Geochem. However, do not use folders such as C:\Geochem-EZ or D:\Geochem!EZ (too many characters, special characters).
----------------------------------------------
Running GeoChem-EZ
----------------------------------------------
To launch GeoChem-EZ simply click the GeoChemEZ.exe file or go to the Start bar, click on "Run" and then type "GeoChemEZ.exe" as the file to open. Alternatively, place a Geochem-EZ shortcut on the computer desktop. GeoChem-EZ requires Java SE6 update 7 or higher, which is available for down-load from Sun Microsystems (http://www.sun.com/download/index.jsp).
Configure the program: Select “Options” on the top menu bar and then choose the locations for the default work directory (normally the “MyData” folder), the Metal/Ligand database (usually GEODAT-A.lig unless you have your own database file), and the GEODAT-A.Salts file (found in the resources folder). Default Template is reserved for those users who want to open a specific each time the program starts.
Note: Users may encounter problems with Geochem-EZ if their Windows default language is set to anything other than English (United States). The problem arises when commas are used in place of decimal points. Both XP and Vista users will need to change their Windows default language to English (United States) via the control panel choosing the Regional and Language option before running Geochem-EZ.
If you are receiving error messages and have installed and configured the program properly, then the default language may be the issue.
------------------------------------------------------
Using GeoChem-EZ
------------------------------------------------------
To get a feel for how EZ works, it's best to take a look at the Help files. To get there run GeoChem-EZ, then go to menu bar at the top of the program interface, click on Help and choose “Launch Help”. This will open our Help files in your default web browser. We have found that the Help files display better on the Mozilla Firefox browser (http://www.mozilla.com/en-US/products/firefox/). If you are a seasoned GEOCHEM-PC user, then you can simply open your old "dat" files and get to work. We have included in the My Data folder several example files with the Geochem-EZ “geo” file extension that can be opened with the "load file" option.
-----------------------------------------------------
Critical Files
------------------------------------------------------
As expected, if the files within GeoChem's directory are tampered with, then GeoChem-EZ may crash. The first four files in this directory that should not be moved or altered are:
1) GEORUN.EXE
This contains the executable file for GEOCHEM, which is run by GeoChem-EZ.
2) GEOCHEM.CFG
This is used by GEORUN.EXE and is written anew every run by GeoChem-EZ.
3) Interface.cfg
This file saves all the databases the user selects, along with their default work directory and template. If this is deleted, GeoChem-EZ will revert to a default configuration and generate new file
4) GeoChemEZ.exe
This executable file contains all the precompiled Java files to run GeoChem-EZ.
________________________________________________________________
These next three files can be modified, but with care not to change any of the file structure.
5)metlig.MLW
An exception to the "do not touch rule is this database file, which stores the molecular weights of all the metals and ligands in the GEODAT-A.LIG database. If you expand on this database and wish to use g/L and mg/L in GeoChem-EZ, you can edit this database with any ASCII editor. The format is simply [m/l] [code#] [molecular weight]. The only time that this database should be modified is when metals or ligands are added to the GEODAT-A.LIG database.
6)Resources Directory
This directory contains the default SALTS and LIG databases as well as the entire help system and some images used by EZ. Add your own custom LIG databases here.
All content in this directory should be accessed only through the GeoChem-EZ program.
7)'MyData' Directory
This is the default directory to store all of the user’s *.geo files. Upon
installation of the program, it will contain example files in both DAT and GEO formats.
There may also be a number of temporary files with GEOCHEM-EZ in its run of GEOCHEM-PC. Destroy these at will.
