Check this option to specify whether or not you want to create an Update.exe installation launcher for the current patch.

The Update.exe installation launcher is required in the following cases:

- You are building a release for an InstallScript MSI project.

- You want to automatically update or install the Windows Installer service on a target system, when necessary.

For Basic MSI projects, creating Update.exe is recommended if your installation program uses InstallScript custom actions. If necessary, Update.exe installs the InstallScript engine files on a target system by launching ISScript.msi.
