The IExpress tool is native to Windows operating systems. It creates a self-extracting package, for example a Setup.exe file, and contains one or more other files that users extract from it. Creating a Setup.exe file allows you to easily distribute your software applications or games to others in a single executable file rather than forcing them to download multiple files. Not all Setup.exe files contain installation commands, especially smaller programs. When you use IExpress, you designate whether the package you create will have an installation command or not.
