InstallScript MSI and InstallScript Silent Installations

InstallShield 2022

Project:This information applies to the following project types:

• InstallScript
• InstallScript MSI

InstallShield Silent allows automated electronic software distribution, also known as silent installation. With InstallShield Silent, there is no need for end users to monitor the installation and provide input through dialogs. An InstallShield Silent installation runs on its own, without any end-user intervention.

If there are multiple instances of your application on a machine, and if a silent update installation for your application runs on that machine, it applies the update to the first instance that it finds, and it does not display the Qualifying Product(s) Detected dialog.

To launch InstallShield Silent, use the Setup.exe -s command line parameter.

You can run your installation with the Setup.exe -r parameter to select installation options and automatically record the InstallShield Silent response file, or you can create your own. To view a real-world example of a response file, refer to the Setup.iss file located on InstallShield installation’s Disk1. For a description of the response file format, see Creating the Response File.

If you need to install an InstallScript MSI installation without using Setup.exe, you can use the MSI silent mode.

To create a silent installation:

1. Create the installation.
2. Create the response file.
3. Run the silent installation.
4. Check for errors.
