Hi there,
IExpress is a component of Windows 2000 and later versions of the operating system are used to create self-extracting packages from a set of files. The IExpress Wizard is a tool that is provided in the Internet Explorer 6 Administration Kit, so the IExpress.exe doesn't exist in all versions of the Windows Operating System.
