back in the year 2007 I started developing a very easy-to-use, free and flexible tool for creating fast setup packages for Windows. It's called InstallForge and supports various features as follows:
Features at a glance
Easy to use
The wizard-driven interface allows you to create your installation packages without scripting knowledge. All you need to do is to fill out the forms and attach the documents that you want the end-user to read.
Customizable user interface
InstallForge allows you to change setup graphics, display a splash-screen, add/remove dialogs and much more.
Multi-language support
InstallForge also allows you to create multi-language installation packages which enable end-users to choose a language they want to be used during the installation.
LZMA support
InstallForge uses the LZMA algorithm for storing setup files, without any limitation (in practice) regarding the size of your setup files.
Visual Update Express support
InstallForge also supports Visual Update Express - a highly flexible update software which you may use in your own projects for free.
