That's an AVG 2014 installer in your screenshot, did you perhaps buy one of the 2015 products?
Eslam, You've used the Online Installer. Try using the 32 or 64 bit Installer whichever suits your system. Have a look @ this article (http://avgclick.me/checkAVGinstall) & click on 'All other installation errors'. If you're not sure about 32 or 64 bit on your system have a look @ this link (http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=140471#post_140471).
