Hi @plaidshirtakos,

If your application has a splash screen or loading screen, please refer to my post:

> [@Error in opening windows desktop application which has splash screen](http://forum.katalon.com/t/error-in-opening-windows-desktop-application-which-has-splash-screen/35882/2):
>
> @balakarthimcet, Please download and install WinAppDriver v1.2.RC and add this property in Windows Desired Capabilties: ms:waitForAppLaunch:25 25 mean the time to wait your application started is 25 seconds, you can increase maximum to 50.
