Unable to instantiate Firefox using Marionette driver over Selenium and C#. os error

Viewed 1785

Could someone please help me with the following issue.

While I'm trying to initialize a browser I get the 'os error' exception.

var option = new FirefoxOptions();
option.IsMarionette = true;
var driver = new FirefoxDriver(option);

var b = new Browser(driver); // Throws an exception with a message - 'os error'

The screenshot of the exception

Plese note, the path to wires.exe is added to the system PATH. Selenium, wires, firefox are of the latest versions. I have tried running using firefox-stable and firefox-developer editions.

Thanks.
