Netbeans IDE6.7.1 Uninstall problem

[Robert Jack]

Hi,

In my system have Ubuntu 11.10, I installed Netbeans 6.7.1

When i try to uninstall the netbeans, i got the following error

The specified target component -nb-base/6.7.1.0.0
was not found in the registry. The installer 
can continue as if the target component was not specified.
Click Yes to continue, No exit the installer.

Help me,
Thanks in advance.
