[🐛 Bug]: Could not find an Internet Explorer window when running Edge in IE mode

[rathimayur]

What happened?

Unable to instantiate InternetExplorerDriver instance on on Windows 11.
Getting below Exception on driver instantiation.

Exception:
Unexpected error launching Internet Explorer. Could not find an Internet Explorer window belonging to the process with ID 5216 within 60000 milliseconds. (SessionNotCreated)

How can we reproduce the issue?

Source Code:
var ieOptions = new InternetExplorerOptions
{
    AttachToEdgeChrome = true
};

ieOptions.EnsureCleanSession = true;
ieOptions.IntroduceInstabilityByIgnoringProtectedModeSettings = true;
ieOptions.ElementScrollBehavior = InternetExplorerElementScrollBehavior.Bottom;
ieOptions.EnableNativeEvents = true;
ieOptions.PageLoadStrategy = OpenQA.Selenium.PageLoadStrategy.Default;

ieOptions.BrowserAttachTimeout = TimeSpan.FromMinutes(1);
ieOptions.ImplicitWaitTimeout = TimeSpan.FromMinutes(1);
ieOptions.PageLoadTimeout = TimeSpan.FromMinutes(1);
ieOptions.EdgeExecutablePath = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe";
ieOptions.IgnoreZoomLevel = true;
string driverPAthWithFileName = @"C:\\Users\\mayurrat\\source\\repos\\TestChromeDriver\\bin\\Debug\\net8.0-windows\IEDriverServer.exe";
InternetExplorerDriverService driverService = InternetExplorerDriverService.CreateDefaultService(driverPAthWithFileName);

try
{
    Driver = new InternetExplorerDriver((InternetExplorerDriverService)driverService, ieOptions, TimeSpan.FromSeconds(Convert.ToInt32(600)));
}
catch (Exception ex)
{

}

I've only seen this error with the combination you mention if the code is being executed under an admin user.

You can try to set IgnoreProcessMatch to true.

See 1976dbe

Thanks, seems working with basic code, still let me verify the same.
BTW what could be the root cause ? Is there anything related to Windows 11.
Also I don't see mention of Windows 11, in docs of IEDriverServer.exe on below URL

Running the script in admin mode is the root cause, but I don't know if that is your case. There is no mention of this because we have not updated the docs. Would you like to improve those based on your findings?
