All known file formats using extension .INS

While InstaCalc Spreadsheet is a popular type of INS-file, we know of 12 different uses of the .INS file extension. Different software may use files with the same extension for different types of data.

InstallShield Script

InstallShield Script files with the .INS extension are compiled installer scripts created by the InstallShield tool. These files store the executable logic for Setup.exe in legacy InstallShield projects - mostly InstallScript or InstallScript-MSI project types. The compiled .INS may be bundled with or run by Setup.exe to provide scripted installation behavior on Windows systems.

The .INS script file is not human-readable source code: it is the binary compiled form of a developer's installation logic (written in InstallScript/RUL files). Setup.exe uses the script during installation, either from the same folder or specified via a command-line switch. If Setup.exe cannot find the compiled script file (usually named Setup.ins or similar), it produces an error about missing script files.

For setups built with InstallShield versions prior to or including InstallShield Script and InstallScript-MSI, Setup.exe supports a "/f

Binary signature patterns include a magic header of bytes B8 C9 0C 00 at offset zero. The .INS file usually contains many internal keywords used by InstallShield (such as TARGETDIR, SRCDIR, PROGRAM, UNINST, etc.), which help identify it as an InstallShield compiled script.
