Adding a VBScript or JScript Custom Action to Your Project
Chapter 10: Customizing Installation Behavior
Using Custom Actions
The items in the Custom Actions view are organized by chronological order, according to when they are
launched during installation, maintenance, or uninstallation. When you add a custom action to your
project, you specify when the custom action should be launched by adding the action to the appropriate
installation, maintenance, or uninstallation item.
Task To add a VBScript or JScript custom action to your project:
1. In the View List under Define Setup Requirements and Actions, click Custom Actions.
2. In the Custom Actions During Installation explorer, the Custom Actions During
Maintenance explorer, or the Custom Actions During Uninstallation explorer, click the item
that should contain the custom action that you want to create.
3. Right-click the item and click New VBScript or New JScript. InstallShield adds a new custom
action with the name NewCustomActionn (where n is a successive number).
4. Type a name for the custom action.
5. Configure the settings for the custom action.
Configuring a VBScript or JScript Custom Action’s Settings
When you add a VBScript or JScript custom action to your project, you need to configure its settings.
Task To configure the settings for a VBScript or JScript custom action in your project:
1. In the View List under Define Setup Requirements and Actions, click Custom Actions.
2. In the Custom Actions during Installation explorer or the Custom Actions during
Uninstallation explorer, click the custom action that you want to configure.
3. Configure the settings in the grid on the right.
