So i wanted to download the latest driver for my intel hd 4600 (220.127.116.11.4080),
and i deleted the old driver and download the latest.
So i started the instalation and I got this error : http://pokit.org/get/img/2b5b0111b06d7aa216009c186ec7f497.jpg
This error usually appears when there are customized drivers installed on your computer and then it blocks the installation of generic drivers.
Bear in mind that we provided generic drivers; and sometimes these cannot be installed on other systems or the installation of them could overwrite their customizations and possibly change the functionality of the graphics.
I would like to verify some more information about your system. Can you please post the dxdiag report here?
