The Prerequisite Properties Tab

In this tab you can edit the properties of a new prerequisite or change the properties of an existing one.

Display

This section contains the information shown to the end-user when the prerequisite wizard is launched. Note that this information does not affect in any way the prerequisite.

Name

The name of the prerequisite. This information will be shown to the user in the prerequisites wizard and does not affect the prerequisite detection or installation.

Ver Min

The minimum version required, for the prerequisite to be installed. This information will be shown to the user in the prerequisites wizard and does not affect the prerequisite detection or installation.

Ver Max

The maximum version required, for the prerequisite to be installed. This information will be shown to the user in the prerequisites wizard and does not affect the prerequisite detection or installation.

This information will let the end-user know what prerequisites must be installed in order to install your application.

Setup File

Location

The "Location" combo box allows you to set the location of the installation package for the prerequisite. The available options are:

• File in package - this option allows you to specify an installation file on the disk which will be added to your installation package files.
• URL - this option allows you to set the URL which points to the installation file of the prerequisite. This option requires the exact size of the installation package and its MD5 signature for verifying if the prerequisite is downloaded correctly or not. Also, the URL you use must point directly to the installation package of the prerequisite. If it uses redirection then the installation package of the prerequisite will be saved with an invalid name.
• Open Site - this option will open the website you set for the prerequisite, allowing the user to select the prerequisite version he wants installed. In this case, the prerequisite wizard will wait until the user clicks the "Finish" button in the wizard before verifying if the prerequisite was installed correctly or not.

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.

Command Line

An optional command line for launching the prerequisite. Special parameters (like silent install) can be passed to the installation package of the prerequisite by using this field.

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

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 File In Package prerequisites.

64 Bit

Specify whether your prerequisite is a 64-bit application and it uses a 64-bit installation package.

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.

You 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.
