Hi,
When trying to uninstall some software I am getting the exception as

java.lang.NullPointerException

at merlin.wizard.core.WizardConsole.run(WizardConsole.java:129)
at java.lang.Thread.run(Thread.java:492)
The uninstall process never terminates and the windows have to
manually be closed.

I think many people faced this problem before. Can anybody explain why this happens.

Thanks in advance
