After downloading, double-click on jchem_windows_VERSION.exe or jchem_windows_v64_VERSION.exe .
Go through the installation wizard.
Installer supports silent installation (non-interactive mode without GUI). To run installer in silent mode, give the -q command line parameter by launching the installer. In silent mode, previous JChem version (if exists) will be uninstalled automatically.
If you are not sure that Java is installed, you can check it by the following way:
Select Command Prompt from the Accessories sub-menu in the Start menu.
Type the following commands in the opened Command Prompt window: java -version
You will get the following error message if Java is not available on your machine:
'java' is not recognized as internal or external command, operable program or batch file
If Java has been installed, the version number of Java will be printed:
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
Mac OS X Instructions
After downloading, double-click jchem_macos_VERSION.dmg.
Go through the installation wizard.
After the installation process, add the bin folder of the jchemsuite folder to the PATH to be able to run JChem applications from any directory in command line.
Requires Mac OS X 10.3 or later
The compressed installer should be recognized by Stuffit Expander and should automatically be expanded after downloading. If it is not expanded, you can expand it manually using StuffIt Expander 6.0 or later.
If you have any problems launching the installer once it has been expanded, make sure that the compressed installer was expanded using Stuffit Expander. If you continue to have problems, please contact technical support.
Installer can be run also in silent/non-interactive mode, just give the -q command line parameter by running of the installer. In silent mode, earlier installed JChem version will be uninstalled automatically.
Linux / Solaris Instructions
After downloading, open a shell and enter into the directory where you downloaded the installer.
At the prompt type: sh ./jchem_unix_VERSION.sh
After the installation, add the bin subdirectory of the jchemsuite directory to the PATH to be able to run JChem applications from any directory.
You need to install a Java Runtime Environment 8 (or later). You can download it from Oracle's web site or contact your OS manufacturer.
If the installer does not start, check whether JAVA_HOME/bin is in PATH (where JAVA_HOME is the directory of Java).
To chech it, type the "which java" command that shows the location of the java launcher. You should get something like this:
If java is missing from PATH, you will see something like that:
/usr/bin/which: no java in (/usr/bin:/opt/apache-ant-1.6.1/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/vertset/bin)
Installer supports silent mode (non-interactive mode, without GUI). To run installer in silent mode, give the -q command line parameter at startup. When installer runs in silent mode, earlier installed JChem will be uninstalled automatically.
Instructions for All Other Platforms
After downloading go to the directory where you downloaded jchem_platform_independent_VERSION.zip then uncompress the zip file.
You can start applications by script or batch files, which you can find in the jchem/bin directory.
Requires Java 1.6 (or later). You can download it from Oracle's web site or contact your OS manufacturer.
You need an expander which can handle zip extension.
How to uninstall
Use the uninstaller to remove JChem from your machine.
Double click on uninstall.exe in the JChem's home folder or select JChem from the Add / Remove programs list on Control Panel.
Double click on the uninstall in the JChem' home directory.
Linux / Solaris
Launch the uninstall script in the JChem' home directory.
If you give the -q command line parameter, uninstaller will run in silent mode (without GUI, no user interaction).
