Opening IST files

Did your computer fail to open an IST file? We explain what IST files are and recommend software that we know can open or convert your IST files.

What is an IST file?

Files that contain the .ist file extension are project template files that have been created by the InstallShield software. The InstallShield application is commonly used to create .msi Windows Installers and installation packages for software developers.

The .ist files that are created by the InstallShield software contain a template that stores default settings, design elements, directory structures, custom scripts, code, images and text. This allows the developer who is creating the installation package to create packages for multiple applications without having to start the development of each installation application from scratch each and every time, saving the developer time and allowing him to create more installation packages in a given time period.
