You have to provide full server file path with name of executable file -
System.setProperty("webdriver.ie.driver", "C:\\Users\\Anupam\\Downloads\\Software\\[b:3v4rmep5]IEDriverServer.exe[/b:3v4rmep5]");
while running on chrome it's a message, you just ignore it -
[b:3v4rmep5]Starting ChromeDriver 2.20.353145 (343b531d31eeb933ec778dbcf7081628a1396067) on port 8530
Only local connections are allowed.[/b:3v4rmep5]
System.Environment.SetEnvironmentVariable("webdriver.chrome.driver",@"/path/to/where/you/ve/put/chromedriver.exe")
