What Operating System do you have installed?

Likely only the 64 bit driver is listed (many of the drivers are 32 and 64 bit but the Intel graphics isn't). If you installed the 32 bit version of WIndows 7 or Windows 8 it makes sense for the error message to display. Also if you are installing the 32 bit OS, why?

Hi,

Thanks for the reply.

I have windows  8 64bit installed on my computer with switchable graphics. The AMD driver is up to date but cannot update the intel drver. I have only been downloading the driver 64 windows 8 driver from the dell driver page.

i get this message under the graphics section after running the intel utility

A customized computer manufacturer driver is installed on your computer. The Intel Driver Update Utility is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues. Contact your computer manufacturer for the latest driver for your computer.

Cay you not help me any further

Was it this driver you tried to install?

If that fails try running the Intel update Utility

yes thats the driver. I just tried to install it again and it does not work. Keeps on saying unable to install as my system does not meet the minimum requirements.....

I can download a driver update from the device manager or windows update but after it is installed it then causes a problem for the amd graphics card so dont want to do this.
