Sorry you're having trouble with the installation. Check in the installed programs to see if an older version of the utility might be installed. If it is try uninstalling the old version before installing the new version.
A workaround to using the Intel Driver Update Utility would be to manually download the updated driver. If you're not sure what Intel components are in your PC, you can use: Intel® System Identification Utility - Identify Your Product..
You can then type the model number of the device component in the Intel® Download Center. When you start to type the device information into the search box, you should see the device name appear and you can click on it to get the list of available drivers and software.
I'm guessing the game wants you to upgrade a graphics driver. I don't know what model graphics you have, but this example should work for any model. Here is an example for my Intel HD Graphics 4400. I didn't have to type the entire name. I just clicked on the product name that popped up and it took me to the list of drivers.
I hope this helps.
