Install

UI Level

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

Configure

Click on this hyperlink to configure the UI Level switches.

Command Line

NoteThis field is not available for Chained prerequisites

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 used to call the prerequisite, the same for the rest. Click on Configure hyperlink next to UI Level to have different command lines for each UI level. The Edit UI Level Dialog will be displayed.

  • Full UI - command line parameters used for an installation with the full user interface
  • Basic UI - command line parameters used for an installation that shows only a progress bar
  • Silent (no UI) - command line parameters for an installation with no user interface

ImportantIf you need to omit a parameter containing an empty property from the install command line of a prerequisite, you could place it between curly brackets - "{ }" . For example :" {PROP=[CHEKBOX]} ". In this case, if CHECKBOX property is empty the whole expression will be omitted.

ImportantThis field does not support Formatted values for Framework prerequisites.

NoteThe command line of a prerequisite accepts all the standard MSIEXEC parameters if the prerequisite's installation package is MSI-based.

ImportantDepending on the UI level configured for the prerequisite, the UI level switches will be appended to the command line of the prerequisites. Advanced Installer does this by appending the [AI_PREREQ_UILEVEL_SWITCH] property to the cmd specified in the Command Line field. This property will be resolved according to the UI level of the package.

Properties

NoteThis field is only available for Chained prerequisites

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

NoteThis 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
  • During Main Package
  • After Main Package

NoteFor 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.

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

Caution!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.

Chained

Check this option to install the prerequisite as a Chained Package

Framework

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

NoteCheck 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.

Uninstall

Allow Uninstall

Check this option to allow the uninstall for the prerequisite
