Hi, Can you please help check: - Install WinAppDriver version 1.2 onwards. You can download the latest WinAppDriver version from the WinAppDriver GitHub project here: [WinAppDriver](https://github.com/microsoft/WinAppDriver). - Try Start application with title [https://docs.katalon.com/katalon-studio/keywords/keyword-description-in-katalon-studio/windows-keywords/windows-start-application-with-title#ar[…]e1](https://docs.katalon.com/katalon-studio/keywords/keyword-description-in-katalon-studio/windows-keywords/windows-start-application-with-title#ariaid-title1) As well, it will be much better if you can show us the recording. Thank you! ---

1. I have winapp driver installed which is version 1.2 onwards. 2. I have tried with Start application with title but getting same error. I have kept “ms:waitForAppLaunch”: “50”, once i clicked on run windows first step which is Start application with title is failed in 13.1638 sec. why it is failing before wait time which is “ms:waitForAppLaunch”: “50”.. ![image](https://europe1.discourse-cdn.com/katalon/original/3X/1/d/1d5442a0cbc5a5b70c11595db6274c7fdda162a0.png) Please reply asap. ---

hi @schakarwar two things from your post. the step fails in 13 seconds while you set ms:waitForAppLaunch to 50, so the capability is not being applied. in katalon’s desired capabilities the value type matters, that one has to be Number, not String, winappdriver ignores “50” in quotes. check the type column in Project \> Settings \> Desired Capabilities \> Windows. even with that fixed, the error text “failed to locate opened application window with appId C:\Users\F.exe” means winappdriver never saw a top level window owned by the process it launched. apps that start through a launcher or splash process (the first exe exits and spawns the real one) always do this, no matter how long you wait. the fix for those is to launch the exe yourself and attach to the window by title: ```groovy Runtime.getRuntime().exec('C:\\Users\\F.exe') WebUI.delay(30) Windows.startApplicationWithTitle('your main window title') ``` grab the exact title from the window after it is fully up. once you attach that way the waitForAppLaunch cap does not matter at all.
