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.
Additionally, run Combofix and wait for the process to complete because this application is considered as being malware due to the offers, pop ups, adware and possible trojans it prompts you to download and install.
