step 2:

  I have updated the testscript as follows:
ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=C:\\Users\\pgudi\\AppData\\Local\\Google\\C
hrome\\Application\\35.0.1916.114\\Extensions");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
oBrowser=new ChromeDriver(capabilities);

and in this path 
C:\Users\pgudi\AppData\Local\Google\Chrome\Application\35.0.1916.114\Extensions
I added the following files (Manually)
i.icon.png
ii.manifest.json (this file inturn has the following lines
     {
      "name": "My First Extension",
      "version": "1.0",
      "manifest_version": 2,
      "description": "The first extension that I made.",
      "browser_action": {
       "default_icon": "icon.png"
      },
       "permissions": [
       "https://preview.dentalweb.com"
      ]
      }
iii. external_extensions.json (this file exists bydefault,it has the content as 
follows

// This json file will contain a list of extensions that will be included
// in the installer.

{
}

After performing above settings
I started running the script to capture screen shot,it works inconsistent 
approach some time(in the same package) it captures screen shot and some time 
(other package)it displays the following 
exception

I am able to duplicate this problem at will using ruby with chromedriver. 

Ruby 2.0.0-P598
Selenium 2.44.0
ChromeDriver 2.14.313457

using Atomshell to launch an html 5 application.  Attaching capybara to it, and 
executing

Capybara.save_screenshot('test.jpg')

Throws the exception:

Ran below sample ruby code without capybara and able to capture screenshot 
successfully.

Please try without Capybara and let us know if you still facing issue with 
latest chromedriver:2.16

Sample Code:
require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome
driver.navigate.to 'http://www.google.com'
driver.save_screenshot('google.png')
driver.close

I am facing the same issue using python: WebDriverException: Message: unknown error: cannot get automation extension E from unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html

[Tom331]

I am getting the same error as @oliaLi but I am using protractor with selenium-webdriver. But I am not trying to take a screenshot, the error occurs for me whenever I use browser.manage()
