First I would like to say thanks for your valuable help.
I have followed the steps according to URL you have given. But I have already enabled extensions php_pdo_mysql.dll and php_mcrypt.dll. I have also enabled Apache Module rewrite_module. I am also giving the Secure Connection details according to described on that URL you given. But still the same exception is generated.
The result what I get on my web page is exactly as attachment.
As full page cannot be copied here, I am attaching a text file which contains what I get in result.
