Step Into Actions in the MSI Debugger

InstallShield 2025

You can debug your code when you step into the custom action in the MSI Debugger. You can launch your registered debugger when you step into one of the following types of custom actions:

Windows Installer .dll file custom action
Standard .dll file custom action
Visual Basic Script or JavaScript custom action
InstallScript custom action

To step into the current action in the MSI Debugger, do any of the following:

Click the Step Into button on the MSI Debugger toolbar.
On the Build menu, point to MSI Debugger and click Step Into.
Press F11.

A dialog box opens and asks if you want to launch your registered debugger. Select Yes to launch the deubugger. Select No to step over to the next custom action.

Note:Because InstallShield does not provide the source code for the entry point, you will see some machine code once the registered debugger is launched. You need to click the Step Into button twice to see your code.
