Hello, I’m having trouble automate the windows calculator. When I click on the Window Recorder, give my file path (C:\Windows\System32\calc.exe), and then click start to start the recording, the calculator opens but I got this error message. Please help if you know how to solve this issue. Thank you. java.util.concurrent.ExecutionException: org.openqa.selenium.SessionNotCreatedException: Unable to create a new remote session.

kindly format your code with ``` for better readability ---

To automate the Windows Calculator using Katalon Studio, follow these steps to resolve the common issues with WinAppDriver: ## Step-by-Step Solution: 1. **Use Correct Calculator Path:** groovy ```auto // Use this path for modern Windows 10/11 Calculator String calculatorPath = "Microsoft.WindowsCalculator_8wekyb3d8bbwe!App" // Or try the UWP version path // String calculatorPath = "C:\\Windows\\System32\\calc.exe" ``` 1. **Start WinAppDriver Before Execution:** - Download [WinAppDriver](https://github.com/microsoft/WinAppDriver/releases) - Run it as Administrator before executing tests - Default URL: `http://127.0.0.1:4723/` 1. **Katalon Script Configuration:** groovy ```auto import org.openqa.selenium.windows.WindowsDriver import org.openqa.selenium.remote.DesiredCapabilities // Configure Desired Capabilities DesiredCapabilities capabilities = new DesiredCapabilities() capabilities.setCapability("app", calculatorPath) capabilities.setCapability("platformName", "Windows") capabilities.setCapability("deviceName", "WindowsPC") // Initialize WindowsDriver WindowsDriver driver = new WindowsDriver(new URL("http://127.0.0.1:4723"), capabilities) ``` 1. **Handle UAC Prompt (If Appearing):** groovy ```auto // Add this capability to bypass UI automation restrictions capabilities.setCapability("ms:waitForAppLaunch", 15) ``` ## Troubleshooting Checklist: 1. **Run as Administrator:** - Run Katalon Studio as Administrator - Run WinAppDriver as Administrator 1. **Calculator Version Compatibility:** - For Windows 10/11, use the UWP Calculator path shown above - For older Windows versions, try: groovy ```auto String calculatorPath = "C:\\Windows\\System32\\calc.exe" ``` 1. **Check Calculator Process:** - Ensure Calculator isn’t running in background before test groovy ```auto Runtime.getRuntime().exec("taskkill /f /im Calculator.exe") ``` 1. **WinAppDriver Logs:** - Check logs at `C:\Program Files (x86)\Windows Application Driver\WinAppDriver.log` for detailed errors 1. **Firewall Exception:** - Allow `WinAppDriver.exe` through Windows Defender Firewall ## Alternative Automation Approach: If WinAppDriver issues persist, use Windows native automation: groovy ```auto // Example using autoIT integration Runtime.getRuntime().exec("autoit_script.exe") // Sample autoIT script (calculator.au3) WinActivate("Calculator") ControlClick("Calculator", "", "Button1") // Clicks '1' ControlClick("Calculator", "", "Button23") // Clicks '=' ``` ## Final Verification: After implementation, check: 1. WinAppDriver is running (system tray icon visible) 2. No Calculator instances running before test 3. Correct capabilities set for your Windows version 4. Katalon and WinAppDriver both running as Administrator ---

Did you start the WindowsAppDriver before using the recorder ?
