data:, shown in the chrome url bar when I execute the following Selenium ChromeWebdrive Script. Is the because other instance of chrome browser are working?
Your code looks fine just replace .getProperty() with .setProperty():
.getProperty()
.setProperty()
System.getProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
with
System.setProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
