ISScript 1150 Installer 11.5

ISScript 1150 Installer by KTH is a lightweight utility that installs the InstallScript (InstallShield) 11.50 runtime on Windows systems. Many legacy applications built with InstallShield depend on this runtime to execute their setup logic; without it, installers may fail with “InstallScript engine is missing or corrupted” errors. Use this package to preinstall the required components and improve compatibility with older software distributions.

Key features:

• Installs the InstallScript 11.50 runtime components
• Restores compatibility for legacy InstallShield-based installers
• Supports silent/unattended deployment via standard MSI parameters
• Small footprint and quick setup

Typical use cases:

• Resolving InstallScript engine errors during application installation
• Preparing enterprise images for application packaging and testing

System requirements:

• Windows 7/8/10/11 or Windows Server 2008 R2 and later
• Local administrator privileges

Notes:

• This package does not install or update any target application; it only provides the scripting engine required by some installers.
• A restart may be requested if shared components are in use during installation.
