InstallAnywhere offers Web and CD-ROM installers.

Installer Modes
Web
Web Installers are packaged into a single executable file by platform, and are
appropriate for distribution over the Web or via e-mail. They use a Self-Extractor to

temporary disk space available.

appropriate for Web or electronic distribution. CD-ROM installers are also good for
distribution on DVD, and can span multiple CDs or DVDs.
