About This File
This is a generic 32-bit version of the InstallShield 2 setup engine. This file can be used as a replacement installer for games that use 16-bit versions of InstallShield 2.
To determine if the game uses InstallShield, check the list of files that are in the setup directory (normally, there should be a dedicated folder for the installer somewhere on the game disk). If the file "_inst32i.ex_" is included, then the game uses InstallShield in some form.
From there, the version of the installer currently used needs to be verified to ensure that the replacement file will work. In the setup folder, find a "SETUP.EXE", "SETUP32.EXE", or other similarly named files. Once the installer is found, right click it, select "Properties", and go to the "Version"/"Details" tab. If the "Product version" and/or "File version" fields have a value along the lines of 2.xx.xxx.x, then the game uses version 2 of the setup engine and is compatible with this file.
For specific details on installer use, check the game article that requires it.
