I’m encountering an error while trying to deploy using Katalon with FileMaker. After double-clicking to open and enter my password in the app, I receive the error: “Unable to perform action.” This error prevents me from proceeding further, and I’m stuck at this point.

Has anyone experienced this issue or found a solution? Any help would be greatly appreciated!

HI @developers3,

Welcome to our community. To your problem, I would like to suggest that:

1. **Ensure the WebDriver Session is Initialized Correctly**  
When working with desktop applications in Katalon, you need to initialize the **Windows Application Driver (WinAppDriver)** session properly before performing actions like double clicks. Follow this instruction: [https://docs.katalon.com/katalon-studio/manage-projects/set-up-projects/windows-desktop-apps-testing/set-up-winappdriver-in-katalon-studio](https://docs.katalon.com/katalon-studio/manage-projects/set-up-projects/windows-desktop-apps-testing/set-up-winappdriver-in-katalon-studio)

2. **Increase Timeout or Use Explicit Wait**  
Use some wait or delay before double click

#### 3. **Use the Correct Object Locator**

You can use Spy or Recorder to capture the object first then update to your script

#### 4. **Switch to the Application Window**

If the application is running but not in focus, you might need to explicitly switch to the application window before interacting with it. You can do this using the **Switch to Application** action.

#### 5. **Check the WinAppDriver Connection**

If the session is lost or not properly established, you may need to check the connection to **WinAppDriver** and ensure it is running and listening for commands.

- Make sure the **WinAppDriver** server is running on your system before executing any Katalon scripts.

- You can start **WinAppDriver** from the command line with the following command:

- Verify that the driver is listening at the expected address (e.g., `http://127.0.0.1:4723/`).

Hope this can help. Thank you

Thank you so much for the reply. I have done everything mentioned by the Katalon team above, but I am still getting various errors.

1. Sometimes the screenview look like this.
