# Start Electron Application

The **Start Electron Application** building block starts an Electron application and returns a handle to the Electron window so subsequent Electron blocks can target that window.

Fully expanded, the **Start Electron Application** block shows the following properties:

**Note:** The screenshot on this page uses the **Elegance Design** , introduced in **2025.3**. If you are using an earlier version, your layout may look different.

## Quick-start

1. Drag **Start Electron Application** onto the canvas.
2. Connect the block in the flow and specify the basic parameters required for this block to operate: **Application**. Optionally, you can adjust other parameters if needed.
3. Run the flow when it's ready.

## Building block parameters

Parameters  
* **Block header** : The green input connector triggers the block to begin execution. The green output connector triggers when an Electron application is successfully started. You can rename the block by double-clicking the header text and typing in a new title.
* **Application** : The application to start when the block executes. This should contain the path to the program's **.exe** file. The value can be relative to **Working folder** or it can be a full path. Using **Capture** lets you select an already open application/window or a shortcut that points to an application and captures the needed information into Leapwork.
* **Text fields** : Fields that enable the use of external values (dynamic data) in **Application** . To use a value, right-click the field above where the application path can be entered, select **Insert token** , and insert the field name. Fields can be renamed by double-clicking them, and inserted tokens update their visual appearance accordingly.
* **Working folder** : Sets the base directory for running the command, so paths in **Application** can be relative to this folder instead of fully qualified.
* **Text fields** : Fields that enable the use of external values in **Working folder** . To use a value, right-click and select **Insert token**, then insert the field name. Fields can be renamed by double-clicking them, and inserted tokens update their visual appearance accordingly.
* **Arguments** : Parameters supplied to the program when it is invoked.
* **Text fields** : Fields that enable the use of external values in **Arguments** . To use a value, right-click and select **Insert token** , then insert the field name. Fields can be renamed by double-clicking them, and inserted tokens update their visual appearance accordingly.
* **Window mode** : Controls whether the application window starts as **Normal** , **Maximized** , or **Minimized** .
* **User profile** : Includes the user name.
* **Text fields** : Reflects the configured **User profile** .
* **Error occurred** : Triggers if **Start Electron Application** returns an error during execution, so you can branch your flow.
* **Electron window**: Contains a handle to the Electron window once it is found and focus is set. You can pass this to other Electron building blocks to direct them to a specific window when multiple windows are open.
