HKSetup gives you a template project to create self-extracting zip files. The program Unzip's the zip with internal routines in the windows temporary directory, asks for confirmation, and executes (all of these are options) a exe file.

This is perfect for making Install Shield's setups into one Self-setup Exe file. These routines are NOT encapsulated in a component, nor is the forms unit loaded, so only 80kb are added to the zip file.

I hate to use InstallShield, but I found it necessary when developing BDE enabled applications. But the setup it makes usually contains more files than the original program! One option is to ZIP or to use a Zip to EXE program, but that would need a more experienced user to select a temporary directory, and the again run the Setup.

So this project solves the problem. It has analytical instruction on how to use (very easy). The main logic is the loading of the ZIP file (which you made) into the Delphi program as a resource. When run, the zip is unzipped (with routines that are in the program) into windows temporary dir, and then a program is run. All this is done in the background.

There has been taken special care, using only windows api calls to implement, so that the EXE will not be 300+ kb but only 80kb (without of course the merged zip).
