Most aspects of an InstallAnywhere installer's user interface can be modified. As a
developer of an InstallAnywhere installer, you can alter text strings as well as
graphics, such as the splash screen, installer screens, panel additions, background
images, and billboards. Developers may even add their own animated GIF files to
provide a multimedia experience.

Localization
Nearly every text string in an InstallAnywhere project can be localized. Translations of
the text of built-in InstallAnywhere screens and dialog boxes are already provided.
The Enterprise Edition supports 29 different locales, and the Standard Edition
supports 9.
If developers want to further modify text strings by locale, the string files are output
each time an installer is built, in a folder called "Project locales" which will be next to
the build output folder. The files are named by locale code. For example, the default
English (locale code, en) locale file has the name custom_en.
These locale files contain the text string grouped by the name of the action to which it
belongs. Developers may alter the text string and upon the next build of the installer
the new localized text will be displayed with the action.

Look and Feel
InstallAnywhere provides many options for altering the look and feel of the installer.
Splash Screen
InstallAnywhere installers present a splash screen at the initial launch of the installer.
This screen is displayed for a few seconds while the installer prepares the wizard. The
splash screen is an ideal introduction to your product, and is an opportunity to set the
mood and image for your product. The splash screen will also appear on the HTML
page generated for the InstallAnywhere Web Install Applet. It can be either a GIF, a
PNG, or a JPEG file of any size, although the preferred size is 470x265 pixels.

GUI Panel Additions
The Additions to GUI Installer Panels option allows developers to display a list of
steps or an image along the left side of the installer’s panel.
Background Images
This Background image feature allows you to create a truly unique installer. The
Background image is the graphical background for every panel in your installer.
Background images are only supported in Swing GUI Installers.
Billboards
Billboards are graphics that the installer will display during the installation of files.
Billboards generally convey a marketing message, a description of the product, or
simply something fun for the end-user to see as the file installation is occurring. Each
billboard added will be displayed for an even amount of time, based on actions within
the installation. If an installation has very few files, and many billboards, each
billboard will only be displayed for a short time.
Billboards can be GIF, PNG, or JPEG files, and should be 587 x 312 pixels in size.
Billboards can even use animated GIF files, providing the end-user with a richer
media experience during their installation.
