Opening ISU files

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

What is an ISU file?

Files that contain the .isu file extension are used by the InstallShield software application. InstallShield is a software program that allows users to easily install software applications onto their hard drives. It also offers programmers a way to provide user-friendly installation for their software programs.

An ISU file contains a script that is run by the InstallSheild application when a user chooses to uninstall a software application from their hard drive. The script contained in the ISU file locates and removes all of the files that are associated with the application that the user wants to uninstall when the corresponding program's "Uninstall" command is run.
