Opening ISN files

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

What is an ISN file?

Files that contain the .isn file extension are most commonly associated with installer source files. These files contain listings of the files that are used by the Installshield utility when the utility is installing software applications on a user's computer.

When a user starts to install an application using Installshield, the Installshield utility will use the ISN file to complete the application process, referencing the file to find out where and how to install the application that is associated with it. Without the necessary ISN file, an application will not be able to install properly on a user's hard drive.
