FinishPanel should be the very last panel in order and shows that the installation has been finished successfully.

Additionally it offers the possibility to write a record of the current installation progress including the effective target installation path and user inputs as XML file (automated installer information) which can be used to start the same installer in unattended mode by adding this file as parameter. See Unattended Installations Using Records of Previous Sessions for more details.

To avoid displaying the buttton that creates the installer information file, use the SimpleFinishPanel.
