The ISScript.msi file is associated with the InstallShield software used to extract and run most software installation packages. The file is run automatically when the user initiates the installation of a new software program. Problems with the ISScript.msi file arise when the version on the computer is older than the version used to package the installation program. To run the proper ISScript.msi, the user must determine the required version and install it on the system.
