Timeout when launching Windows application

Last updated: September 2025

When you reach timeout when launching Windows applications, try one of the following ways:

1. Close all unneeded apps and opened folders. Open Katalon Studio only.
2. Remove unused shortcuts on your desktop and your taskbar.
3. Use Windows.startApplication(…) instead of Windows.startApplicationWithTitle(…).

   For example:

   Windows.startApplication('C:\Users\katalon\Desktop\Demo\WindowsFormsApp.exe') Windows.switchToWindowTitle('Main App Title') // Replace this by your main window title
