Now, I set path variable
path : D:..;C:\\Program Files\\Google\\Chrome\\Application
Chrome : C:\\Program Files\\Google\\Chrome\\Application\\chromedriver.exe

You need chromeDriver not Chrome. Start by downloading the chrome driver.
https://sites.google.com/a/chromium.org/chromedriver/downloads
Put it somewhere that your test can access (for example a bin folder relative to your tests).
Now you need to set the environment variable to point the chrome driver.
You can do it from outside the test (for example, as a global setting for your desktop), or from your test setup.
From outside the test
Just set the environment variable webdriver.chrome.driver to point the executable.
(Control Panel -> System -> Edit the system environment variables)
From inside the test
If you're using jython, you need to create a small java library to do that for you
public void setSystemProperty(String key, String value) {
System.getProperties().setProperty(key,value);
}
And use it from your test
Prepare Selenium Driver
Set System Property webdriver.chrome.driver ${EXECDIR}/chromedriver.exe
If you're using Python, you can use the OperatingSystem library
