I am sorry to hear that have had problems installing the latest video drivers.
That message indicates that your computer manufacturer does not allow the installation of generic Intel video drives. You are required to install drivers from your computer manufacturer.
You may try to force the installation of Intel generic drivers by performing manual procedure, see here for instructions:
Select your operating system version and download the zip version of the video driver:
File name: Win64_15338.zip
Thankyou for your reply. I did what you said but i am not able to update drivers when downloaded version 126.96.36.199.3345 zip file and unzipped in a folder and opened device manager then browsed through the folders and selected unzipped folder and clicked Next, then it says"Windows have determined that driver software for your device is uptodate"
But when i verified still it has old version 10.18.10.3308
WiDi is working fine after disabling Windows firewall and Antivirus. However still i cant upgrade graphics drivers with 188.8.131.52.3345. I have contacted ASUS and they will look into the issue but no answer yet.
When you browsed to the unzipped folder did you navigate to the Graphics sub-folder and select the igdlh64.inf file?
Hey mate , you are not alone I have nearly the same problem. I have hp laptop with intel i5 + intel hd 4000. Drivers modified by HP are removed from my pc and installed generic intel drivers version 10.18.10.3958. The intel update tool shows there is newer driver 184.108.40.206.3958 and lets me to download it. Then i unzip the driver folder and hit to install im getting nothing more as 10.18.10.3308 version installed. Even i have cleared the drivers at all and cleaned all software files form the system rebooted pc and then tried to install newer one and again got only 10.18.10.3958 . Seems to be like newer driver pack has older driver inside and im not able to get it updated in any way.
Here is how to do the update.
Download the ZIP file from Downloads for Intel® HD Graphics 4600 (not the .exe)
Create a new folder and extract the zip into the new folder
Go to the device manager and expand display adaptors, then right click to update the driver for HD graphics 4600
Select browse your computer, then 'let me pick', then 'have disk' then browse, then go in the graphics folder in your new folder which you extracted the zip into and select the .inf file.
This will now update your driver.
