I have the same problem Windows 8.1 64bits i5 4670K ( HD 4600 )
In this case the graphics version you currently have(126.96.36.199.4264) is the latest for Windows 8.1. The version 188.8.131.5279 you were trying to download supports Microsoft Windows 10 64-bit, 32-bit on 4th Generation Intel Core Processors.
No Amy, you are wrong:
This is what the link to this driver days in the download center when I sort the drivers to show only windows 8.1 64 bit drivers:
Intel® Iris™, Iris™ Pro, and HD Graphics Production Driver for Windows® 7, 8.1, & 10
This driver includes support for the new Microsoft Windows® 10 operating system and adds new Windows 10 features.
OS: Windows 7, 32-bit*, Windows 7, 64-bit*, Windows 8.1, 32-bit*, Windows 8.1, 64-bit*, Windows® 10, 32-bit, more...
So as you can see, this driver is for windows 8.1 64 bit so the information you are giving us is wrong.
Yes...alright! When we'll(HD 4600, win 8.1 64bits) have the new driver?
Luiz, this driver does work for windows 8.1 64 bits. There is something wrong here and Intel needs to find out why their site lists this driver as compatible with windows 8.1 64 bits but we can't install it
Looks like intel has pulled this driver from their website. It doesn't come up in the search results anymore when you search for "Intel hd graphics 4600." I wonder why...
I would still like to know how to install this driver for windows 8.1...
I also wanted to know when they will release this driver for windows 8.1...
Have your tried with this version Download Intel® Iris™, Iris™ Pro, and HD Graphics Driver for Windows* 7/8/8.1 64bit? That's the latest version available for Windows 8.1 Intel® HD Graphics 4600.
Well Amy I'm going to check when I'm back at that computer and let you know.
In the meantime, can you please check with your people and tell me why this driver that won't install for us says it is for windows 8.1 as well as windows 10?
Actually Amy is not wrong
4th gen such as HD 4600 is only supported for Windows 10.
Well the 184.108.40.20679 driver it's very misleading cause it says it works for windows 8.1 but if you look at the documentation, it's clearly states:
On 6th Generation Intel Core Processors and related Pentium/Celeron:
Microsoft Windows 10 64-bit
Microsoft Windows 8.1 64-bit
Microsoft Windows 7* 64-bit, 32-bit
On 5th Generation Intel Core Processors and related Pentium/Celeron:
Microsoft Windows 10 64-bit
Microsoft Windows 8.1 64-bit, 32-bit
Microsoft Windows 8* 64-bit, 32-bit
Microsoft Windows 7 64-bit, 32-bit
On 4th Generation Intel Core Processors and related Pentium/Celeron:
Microsoft Windows 10 64-bit, 32-bit
I don't see anywhere the driver advertises it will work for 4th gen graphics under Windows 8.1
Documentation exist for a reason.
