Inno Setup Dependency Installer is a set of Inno Setup scripts and a bunch of Pascal code that extends the functionality of Inno Setup installer to provide the possibility of dependencies installation (such as .NET Framework or Visual C++ Redistributable) during installing your product on end-user workstations.
No installation is required. Just download the repository and edit setup.iss file as usual.
If dependencies are needed, the required free hard drive space shown before installation is incorrect.
Special thanks to Ted Ehrich who created the .NET Framework 1.1 script.
I also wanted to thank the community for sharing many fixes and improvements. Thanks guys, please keep it up!
