Edit Property Dialog

Create or edit a property.

Edit Property



In this field, you can specify the property name. When choosing the property's name, you should also decide if the property is private or public.


In this field, you can specify the property's default value. Since this field is Pseudo-formatted, you can use some of the properties available when your custom property is initialized. To select one of them, type the "[" character and select the "Property..." menu.


In this field, you can add useful information about the property as comments.

Hide Property

Prevents the property from being written into the log file. This may be used to prevent the installer from displaying passwords or other confidential information in the log file.

NoteWhen the machine Debug policy is set to a value of 7, the installer writes the property in the log, even if the property is marked as hidden.

Set persistent property

If you enable this option, the property is stored in the registry and available in maintenance mode (repair, uninstall, etc.) and during the upgrade installation.

Secure property

Encrypts the value stored in the property.

Checking this option automatically adds the SecureProp.dll to the project and an internal custom action (AI_SecureProperty) that is executed during the install execute stage, during "Install Execution Stage -> Preparing" action group.

When this custom action runs, the current value of the property (to be secured) is encrypted and the property value is updated to the encrypted value.

The property value will be encrypted only after the install process moves beyond "Preparing" action group. After this stage, if you need to decrypt the value of the secure property you should create your own set of custom action that calls the "GetRevealedTextLength" and "RevealText" functions of our SecureProp.dll.

To learn how to integrate this functionality with your application see the Secure Property how-tos.

Admin property

Allows the property to be saved during administrative installation; meaning when the user installs from an administrative image, this value is used rather than the one stored in the MSI file.

Per Build Values

Configure the property's value for each build.

TipThis section is only available if your project contains multiple builds.


Select a build from your project.

  • Use the default value - use the default value for the selected build
  • Use specific value - specify a different value for selected build
  • Do not include in this build - don't include a property in the selected build
