Prerequisite Setup Files Tab This page allows you to configure the prerequisite files.

Location

A prerequisite package can be retrieved from one the following locations:

  • Use files from disk - this option allows you to specify an installation file on the disk that will be added to your installation package files. Additional prerequisite files can also be selected.
  • Download single file from URL - this option allows you to specify an URL which points to the prerequisite setup file. You can use the installation package exact size and MD5 signature to verify if the prerequisite is downloaded correctly or not. This option supports only single-file prerequisites. You cannot select additional files.
  • Open website in default Internet browser - this option will allow the user to browse the specified website and select the prerequisite version that he wants to install. In this case, the prerequisite wizard will wait until the user clicks "Finish" button in the wizard before verifying if the prerequisite was installed correctly or not.

Main Setup File

File path/URL

This field lets you specify the exact path, URL or website address which contains the prerequisite installation package. The URL field is of PseudoFormatted Type. Use the [ ... ] button to edit the URL using the Edit PseudoFormatted Type Dialog or to select an installation package on the disk.

Folder

The folder name specifies the location where the prerequisite files will be placed, extracted or downloaded. This is a path relative to the download folder for "URL" prerequisites and to the main package folder for the "Use files from disk" prerequisites.

To specify a custom name for the downloaded prerequisite file you can use this format:

<folder_name>?<file_name>
                    
Example: Prerequisites Folder?MyPrerequisite

NoteIn your project "<folder_name>" and "<file_name>" should be replaced with the actual folder and file names. Spaces added before or after the "?" character will be considered as part of the folder or file name.

Save return value in this property

This field holds the name of the property in which the prerequisite installer will store its return value. You can use this property during the install process of your main MSI.

NotePlease note that this field is forced to uppercase characters only due to the fact that only public properties (written in upper-case characters) which are set during Wizard Dialogs Stage will be passed to Install Execution Stage.

Additional Files

In this list you can add additional files required by your prerequisite.

Adding files

You can specify additional files for your prerequisite by using the [ Add Files... ] and [ Add Folder... ] buttons.

NoteOnly files that are in the primary setup file folder or one of its sub-folders can be added.

Removing files

The selected file can be removed from the list by using [ Remove ] button.

Integrity Check

Verify download integrity by

Enable integrity check for the downloaded prerequisite.

Exact size

In this field you can specify the exact size of the prerequisite installation package. This size is used by the EXE bootstrapper to determine if the prerequisite was downloaded correctly.

MD5

This field contains the MD5 signature of the prerequisite installation package. After the prerequisite is downloaded the bootstrapper calculates its MD5 signature. If it's the same as the MD5 signature you specify in this field then the prerequisite was downloaded correctly. If not, the user is notified.

NoteYou can edit these fields directly with the appropriate values or you could use the [ Browse... ] button to compute the size and the MD5 of the file automatically.

Install Command Lines

Optional command lines for launching the prerequisite under different UI environments:

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

ImportantThis field supports Formatted type only if the prerequisite is feature-based.

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

ImportantIf only Full UI command line parameters are specified, these parameters will also be used for both basic UI and silent installations.

Maintenance Command Lines

These options allow you to repair or uninstall the prerequisite when the main package is in maintenance mode.

  • Repair using this command line - repairs the prerequisite when the main package is repaired during maintenance.
  • Uninstall using this command line - removes the prerequisite when the main package is uninstalled.

NoteIf no command line parameters are specified after checking the maintenance options, the MSI will simply launch the prerequisite installer.
