I understand you would like to know why our Intel Graphics Update Utility is not letting you install latest graphics driver in your computer.
Let me apologize for any inconvenience this issue may be causing to you.
We supply generic versions of graphics drivers for general purposes. Computer manufacturers can change the features, incorporate customizations, or make other changes to the graphics driver software or software packaging. To avoid potential installation incompatibilities, we recommend that you first check with your computer manufacturer and use the driver software they provide.
Since your computer comes with two video cards there is a special graphics driver that needs to be install that will make both video cards work fine with each other. This driver is the one ASUS* has available on their website.
If your computer is currently working fine there is no need to update any driver. If you are having graphics issues in your computer let me know more information about the problem you are currently having.
