If the classical way of uninstalling applications doesn't work, then you will need to use an application which tries to remove installed items using advanced tools.
For this type of job, I would like to recommend you an application which has all the needed tools to properly remove faulty applications, registry and temporary files.
Your Uninstaller! uses an advanced set of tools to detect faulty uninstallers and applications. The process of removing is very simple: click on Advanced Uninstall button and locate your application on that list then click Uninstall and wait for the process to finish. There is a limited interaction because the operation is automated.
