Hi everyone i got solution

as i updated my php version 5.2 to 5.6 now.

But got new error

Your PHP Version is 5.6.17, but always_populate_raw_post_data = 0. $HTTP_RAW_POST_DATA is deprecated from PHP 5.6 onwards and will be removed in PHP 7.0. This will stop the installer from running. Please open your php.ini file and set always_populate_raw_post_data to -1. If you need more help please call your hosting provider.

I changed to -1 too.. but its not affecting. and when i called to hosting provider they are not ready to restart the server.

Until it restarts wont it take effect?

You can set in through the root .htaccess file without restarting Apache.
