Edge in IE mode not working with IEDriverServer

Question

I was trying to automate Edge in IE mode using selenium IEDriverServer.exe. When the code runs, I get the error saying "The IEDriverServer version (4.14.0.0) detected in PATH at C:\Users\admin\PycharmProjects\TesteIE\IEDriverServer.exe might not be compatible with the detected iexplorer version (11.0. 19041.3636); currently, IEDriverServer 4.14.0 is recommended for iexplorer 11.*, so it is advised to delete the driver in PATH and retry" I would like to know if Microsoft provides the version recommended for automation, in this case "IEDriverServer 4.14. 0"

Automation approach:

Using the code example available on the Microsoft website. All prerequisites mentioned on the Selenium website have been met.

https://learn.microsoft.com/en-us/microsoft-edge/webdriver-chromium/ie-mode?tabs=c-sharp

Observation:

Even after adding the site to the list of trusted sites, it does not work.

System setup:

Operating system: Win 11 and tested on Win10 both with their updates checked

Edge Browser: 120.0.2210.61

IEDriver Version: 4.14.0.0

I didn't find the version repository.

Please let me know if anyone is facing the same problem and any solution for it, I look forward to your help.

Thanks in advance

I got the same problem. And When I tried to search this message in selenium repo, I found this code:

https://github.com/SeleniumHQ/selenium/blob/83083c63593f245ed82cfd9e43a17654d5f73a43/rust/src/lib.rs#L791-L818

if use_driver_in_path { // <- only calculate when IEDriverServer.exe in PATH
    let version = driver_in_path_version.unwrap();
    let path = driver_in_path.unwrap();
    let major_version = self.get_major_version(&version)?;

    // Display warning if the discovered driver version is not the same as the driver in PATH
    if !self.get_driver_version().is_empty()
        && (self.is_firefox() && !version.eq(self.get_driver_version()))
        || (!self.is_firefox() && !major_version.eq(&self.get_major_browser_version()))
    {
        self.get_logger().warn(format!(
            "The {} version ({}) detected in PATH at {} might not be compatible with \
            the detected {} version ({}); currently, {} {} is recommended for {} {}.*, \
            so it is advised to delete the driver in PATH and retry",
            self.get_driver_name(),
            &version,
            path,
            self.get_browser_name(),
            self.get_browser_version(),
            self.get_driver_name(),
            self.get_driver_version(),
            self.get_browser_name(),
            self.get_major_browser_version()
        ));
    }
    self.set_driver_version(version.to_string());
    return Ok(PathBuf::from(path));
}

I think there is something wrong when matching major versions. And that causes a warn log. It is just a log, not a throw. So I think we can just ignore this log.

Or we can put IEDriverServer.exe in a relative path. Then pass it to the code like this:

service = webdriver.IeService('./IEDriverServer.exe')

with webdriver.Ie(service=service) as driver:
