InstallScript Setup Launcher 16.0

InstallScript Setup Launcher by Acresso Software is the bootstrap executable generated by InstallShield for InstallScript and InstallScript MSI installers on Windows. It is not a standalone application; rather, it initializes and hands off control to the actual setup for a product that was packaged with InstallShield.

What it does:

• Verifies and, if needed, installs the required InstallScript runtime.
• Requests elevation via User Account Control (UAC) and initializes the install environment.
• Extracts temporary files and prerequisites, then launches the main installer.
• Manages language selection, version checks, and rollback behavior.

You’ll typically see it as “Setup.exe” or “InstallScript Setup Launcher” in Task Manager while an InstallShield-based installer is running. Acresso Software (later renamed Flexera) is the vendor behind InstallShield, the tool that produces this launcher.
