Prerequisite Installation Tab

Chained

Use this option to install the prerequisite as a Chained Package. This will ensure that the prerequisite setup installation will be fully handled by Windows Installer and installed synchronously with the main setup install.

Framework

Check this option to install the prerequisite as a Framework Prerequisite.

Check this option only for prerequisites that require no other installation to run while they are installing (eg. .Net Framework). This option will ensure the prerequisite is executed directly by our EXE before any other prerequisite, suspending the current installation and resuming after they finish installing.

UI Level

This field is only available for Chained prerequisites.

Select the User Interface level used by the prerequisite package during product install

• Full UI - the prerequisite will run with Full UI
• Reduced UI - the prerequisite will run with Reduced UI
• Basic UI and progress - the prerequisite will run with Basic UI and progress bar
• Silent install(no UI) - the prerequisite will be installed in silent mode
• Same as main package - the UI level will be the same as the main package's

Command Line

These fields are not available for Chained prerequisites. See UI Level section of this article.

Optional command lines for launching the prerequisite under different UI environments. Each command is used by your prerequisite based on the UI level of the main package, i.e., if the main package runs with full UI the command from the "Full UI" field will be passed to the prerequisite, the same for the rest. This way you can have different command lines for each UI level.

Properties

This field is only available for Chained prerequisites.

A list of installer properties that will be passed to the package (for example MY_PROPERTY="Value")

This field is of Formatted Type and can be edited using Smart Edit Control.

Condition

The condition that determines if the chained package will be installed. Read more in the Chained Package Behavior article.

Scheduled

Specify when to install the prerequisite:

• Before Main Package
• This option will change the build type of the main package into an .exe. In case of silent installations of the main package, an EXE encapsulating both the main and the prerequisite is required to install the prerequisite before the main package. Otherwise, if a .msi build would be used for the main package, the prerequisite will be installed after it because the silent installation of the main .msi packages starts directly at "Install Execution".
• During Main Package
• After Main Package

For Professional project type the "During Main Package" and "After Main Package" prerequisites will be installed only if the main package is run with full UI. The prerequisite will not be installed if the main package is installed with silent or basic UI.

Reboot system after installing this prerequisite

The user will be prompted to reboot the machine after the prerequisite is installed. If the user accepts a reboot, the machine will be automatically restarted and the installation will continue, otherwise the installation will be aborted.

Continue with main installation even if the prerequisite is not installed

When this option is unchecked, the main product installation will not fail as in case of a launch condition but it won't be allowed until the prerequisite is installed.

It is recommended to also have an appropriate launch condition for each prerequisite set with this option.

Enabling this option for prerequisites scheduled during the main package installation will not rollback the installation when the prerequisite fails if you're running the main package in silent mode. This is happening because during a silent installation the prerequisite will be installed after the main installation when it's too late to rollback.

Allow Uninstall

Check this option to allow the uninstall for the prerequisite.

UI Level
