D. INSTALLING
Installing GCLAS
----------------
Prior to installation, it is recommended that you remove (or rename the directory
of) any previously-installed version of GCLAS.
Depending on the operating system and security settings, it may be necessary to
install GCLAS using administrative rights. This may require that you log in as
administrator and run the installer or open a command prompt as administrator
and run the installer via the command line as discussed below.
To install the software, double-click gclas_install_1_06c.jar to execute
the installation program and follow the directions on the screen. If the
installation program does not start when double-clicked, open a command
window in the directory that contains gclas_install_1_06c.jar and then type:
java -jar gclas_install_1_06c.jar
Follow the installer's instructions to complete the installation.
By default, the software is installed in the directory
C:\Program Files\USGS\gclas1.06. This is the recommended installation
directory, but you may use other directories or disk drives.
GCLAS directory structure
-------------------------
The following directory structure will be created (the contents of each
directory are shown to the right):
gclas1.06 files NOTICE.TXT and this README.TXT
`-----bin batch file to run GCLAS
`-----data example input data
`-----doc documentation files
`-----help file containing on-line help text
`-----lib class files and software libraries
`-----lib_data constituent library files
`-----user working directory used by GCLAS shortcuts
`-----Uninstall uninstaller for GCLAS
E. RUNNING THE SOFTWARE
Select the GCLAS shortcut from the Start menu to execute GCLAS. The
Start menu shortcut is found under Programs, in the Program Folder
specified during installation (default: USGS).
See the GETTING STARTED text in the upper right-hand panel of the
GCLAS window and the on-line help for assistance with using GCLAS.
Users with multiple installations of JRE should note that the batch
file executed by the GCLAS shortcuts will execute the first java version
found by the operating system. To execute a different java version,
uncomment and modify as appropriate the lines containing the jrehome
variable in the batch file that executes GCLAS.
F. UNINSTALLING GCLAS
To uninstall GCLAS, open a command prompt window (as administrator if
permissions require) and type:
java -jar C:\Program Files\USGS\gclas1.06\Uninstall\uninstall.jar
and follow the prompts. If GCLAS was not installed in the default location,
substitute the correct path to the Uninstall directory.
