Files that contain the .iss file extension are InstallShield silent response files. These files are used by the Windows InstallShield software application. Windows InstallShield is a program that helps users install software applications on their systems and also allows developers to use a seamless installation process for their software products.
The InstallShield software was originally developed in 1992 by Stirling Technologies. The ISS files that are used by the InstallShield program contain the settings for the associated program that is being installed and the files are used during process of the software installation. These files are normally saved in a text-based file format.
