System Requirements

1. PC installed with Java virtual machine (Java VM, JDK v5 update 06 or above is suggested for WinXP users); most iMac has been built-in Java VM together with computer hardware, and thus doesn’t require installing any Java VM again if it is the case.  However, Mac OS X users will need JVM v1.4.2 for successful registration.  One simple way to test if Java VM has been installed or not on either a Mac or a PC: open a terminal (Mac) or run ‘cmd’ (on WinXP) and run the command ‘java –version’ to see if there are appropriate message showing on your screen.
   
   To check if your system has been installed Java VM (for example, JDK v6.0)

   c:\>java –version [Enter] c:\>java version "1.6.0" Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-b64) Java HotSpot(TM) Client VM (build 1.6.0-b64, mixed mode, sharing)

   
   or similar.  The only difference may just be the version numbers.
   To run JGuiB: type “java –jar JGuiB.jar” or just click JGuiB icon from JGuiB program folder at Windows "Start" menu if you're using  provided setup file to install it.
    

2. MacOS X for Mac or Win 9.x/ME/XP for PC or Linux-PC Intel x86 (Fedora Core 4/5).  For Linux-PC users, if the installation file does not work nicely, please do it manually as follow.  First you should download the .zip file for MacOS X first.  And then download JRE from SUN website and install it.  Unzip the JGuiB zip file to a directory you like, and run it with "java -jar JGuiB.jar".  It should work in this way.  In some PC, our installation (setup) file may not work properly.
