Eclipse 3.0 JVM Terminated Exit Code =1

Hello all,
Kindly help me setting up Eclipse at my PC. I am running a Windows 2000 box, copied the Eclipse folder which is running on a friend's PC. Now when I am clicking the Eclipse.exe application, it is coming up with the JVM Terminated Exit Code=1 problem. I have searched for the answer of this problem and I realized that the Classpath and path of the JDK should be configured properly. I have done that configuration and ensured that no other JVM except 1.4 is installed on my machine (though there was one previously, but i removed it) but I am still getting the same error i.e. Exit Code =1. I, then tried to running that command that comes with the error message through DOS prompt but nothing happened. I therefore realized that I was using a beta version of JDK1.4.1. Hence, I request you all to use a non-beta version of the Development Kit. It costed me almost 2 days to troubleshoot.
Regards.
