Hi Mark,

It doesn't matter if the uninstaller is run in GUI mode or in command
line mode. It still doesn't finish its job.

The problem seems to be that the installer runned with GUI creates an
uninstaller different from the one created by the AutomatedInstaller.
In fact, the difference is that the GUI-mode-generated uninstaller.jar
file has three more files at the end of the archive, namely:

rootScript
uninstallerJars
uninstallerListeners

and the uninstaller error from my previous mail seems to have been
caused by the absence of a rootScript file.

I took some time to look in the source code and I think that the
problem might be in the
writeUninstallData()  method found in
       com.izforge.izpack.installer.AutomatedInstaller.java
and also in
        com.izforge.izpack.installer.InstallerFrame.java

They seem to be quite different even though the comments say:
    /**
     * Writes the uninstalldata.
     *
     * Unfortunately, Java doesn't allow multiple inheritance, so
     *     <code>AutomatedInstaller</code>
     * and <code>InstallerFrame</code> can't share this code ... :-/
     *
     * TODO: We should try to fix this in the future.
     */

Thank you for the quick response. Keep me posted :-)

Best regards,
Marius Nicolae
