Uninstall configuration
UninstallText	text [subtext]	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Specifies the text on the first page of the uninstaller. If subtext is specified and not empty, it will replace the default secondary text on that page, "Uninstall from:".
UninstallExeName	exename.exe	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Specifies the executable name of the uninstaller. The uninstaller will be created in $INSTDIR at the very end of the install (after the last section is executed, but before .onInstSuccess). Note that to have an uninstaller created, an Uninstall Section must be created.
UninstallIcon	path_to_icon.ico	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Sets the icon of the uninstaller. Again, the icon MUST contain a 32x32x16 color icon resource (it can also contain other icons, but they will be discarded).
UninstallCaption	caption	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Sets what the titlebars of the uninstaller will display. By default, it is 'Name Uninstall', where Name is specified with the Name command. You can, however, override it with 'MyApp uninstaller' or whatever. If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string)
UninstallSubCaption	page_number subcaption	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Overrides the subcaptions for each of the uninstaller pages (0=": Confirmation",1=": Uninstalling Files",2=": Completed"). If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string)
ShowUninstDetails	hide | show | nevershow	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Sets whether or not the details of the uninstall are shown. Can be 'hide' (the default) to hide the details by default, allowing the user to view them, or 'show' to show them by default, or 'nevershow', to prevent the user from ever seeing them. Note that sections can override this using SetDetailsView.
UninstallButtonText	[button text]	Replaces the default details button text of "Show details", if parameter is specified (otherwise the default is used). Changes the text of the button that by default says "Uninstall" in the uninstaller. If no parameter is specified, the default text is used.
