T470 (type HD20, HE20): Intel HD 520 Graphics not working in Windows 7 Pro 64-bit

The computer came with Windows 10 when I got it a while ago, and recently I've decided to put Windows 7 on it instead. This process has been fraught with peril: I had to mount an ISO and manually add USB 3.0 drivers - and use Rufus to create a UEFI bootable stick - just to be able to install Windows 7 in the absence of an optical drive; I had to manually install Ethernet and Wifi drivers; etc. I've fielded those problems on my own, but I'm stuck on getting Windows to use or even recognize my Intel HD 520 integrated graphics: it shows up as "Standard VGA Graphics Adapter" in the Device Manager, and even in the Intel Driver & Support Assistant - https://i.imgur.com/4AGEmjd.png

Trying to run DirectX games such as League of Legends gives me this error - https://i.imgur.com/v2tPy5t.png

And so a fix must be found!

In effort to fix this trouble, I went to the Lenovo website. Unfortunately, the T470 doesn't have a Windows 7 graphics driver listed; so, I went to Intel. They do list two possible downloads:
+ 15.45.23.4860 (for 6th Gen Only) https://downloadcenter.intel.com/download/27360/Graphics-Intel-Graphics-Driver-for-Windows-15-45-?pr...
+ 15.40.14.4352 (for 6th Gen) https://downloadcenter.intel.com/download/25620/Intel-Graphics-Driver-for-Windows-7-8-1-15-40-6th-Ge...

I've tried both of those download links. Each successfully runs the installer, which reads and extracts files, then I am presented with this error - https://i.imgur.com/XJy16zY.png

Windows then gives me a notification that the driver may not have installed correctly, and prompts me to try again with recommended settings. Again the installer reads and extracts files, then gives me this slightly different error - https://i.imgur.com/M41cd24.png

I know people successfully run Windows 7 on T470s, but I have hit a snag I do not know how to overcome. Assistance is appreciated! It's worth noting that these issues did not occur when running Windows 10.

Hi emasks, and welcome to the Lenovo User Community! Are you sure the T470 has an 6th Generation Intel CPU? It sounds like you're trying to install on a 7th Generation Intel CPU (not compatible with Windows 7). What is the exact T470 model, 20xxxxx?

I don't work for Lenovo. I'm a crazy volunteer!

I am using a 7th generation processor, and that was the problem.

 

Solution was found in this thread on Tom's Hardware: http://www.tomshardware.com/forum/id-3413666/guide-installing-windows-kaby-lake.html

Literally as simple as copying the code from the Windows 10 section of the driver INF to the Windows 7 section.
