Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
If in any case the product is detected as adware, AdwCleaner will wipe it from your system by deleting is child processes, registry entries and autorun entries.
