From Disoriented Labs:
FreeExtractor creates self-extracting archives for Windows from existing ZIP files. It is an open-source solution for packaging software programs and distributing files to friends and colleagues over the Internet. It features a Windows 2000-style wizard-based user interface. Authors have fine-grained control over archive settings and can tailor their self-extractors to suit their applications. Authors can specify such options as an embedded URL, introduction text, shortcut creation, and a custom icon.
