installing LCES on RHES but stuck at "Creating uninstaller..."

Hi there,

I'm installing the trial LCES on RHES but stuck at "Creating uninstaller...".
The progress bar is working so it seems the installer is not frozon though.
But anyways, I've been waiting for over 10 hours but nothing changed. ;(

Has anyone got the same problem ?

Here is the description of my system --------

OS version: ( % cat /etc/redhat-release )
Red Hat Enterprise Linux Server release 5.1 (Tikanga)

Java version: ( % java -version )
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Client VM (build 1.5.0_15-b04, mixed mode, sharing)

CPU: AMD Opteron 2.6GB
Memory: 1.7GB
Available space of HD: 160GB

Thanks.

Jack
