What are ISN files and how to open them
Are you having problems opening an ISN file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your 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.
