In this window you are invited to choose uninstall options. It is important to choose the correct options.
Automatic (full) uninstall uninstalls everything that the application has installed.
Custom uninstall shows you every action that the uninstaller will perform before uninstalling and enables you to select which actions you want it to perform and which actions to simply ignore. This is useful especially if you kept other program running while monitoring the application's setup. Advanced users may want to always choose this option in order to examine which application items will be removed.
If the When uninstalling application items perform a backup of each item checkbox is checked the monitor will perform a full backup of the application before uninstalling it. That backup can be restored later using the restore application option.
It is recommended to always check the backup checkbox described above, because if anything goes wrong after the uninstall, you will be able to undo the uninstall - that is, to restore the backup in order to revert your computer to the state it was before uninstalling.
After you choose the uninstall options you want, you can press the Next button to uninstall the application.
