How-to: bypass "The driver being installed is not validated for this computer"

[SXX]

If you reading this message it's mean you met problem within Intel driver installation process. This error message mean that your laptop manufacturer blocked generic driver installation for your laptop and in most cases there it's done for completely no reason.

Drivers on laptop manufacturer websites outdated most of time so using generic drivers it's only case for your problem with graphical glitches or crashes.

Note: drivers distributed though Windows Update are broken for this game.

Can generic drivers cause issues with my hardware?

If your laptop/tablet only have Intel HD graphics card then driver update won't cause any issues because Intel HD graphics built right into CPU and laptop manufacturers can't modify it.

If your laptop have hybrid or dual graphics (e.g Intel+AMD or Intel+Nvidia) drivers than update of Intel drivers might affect discrete graphics card. So if you have two graphics cards it's recommended to update drivers to both of them to avoid issues.

Prepare for driver installation

Before you start to install new drivers you need to prepare your system:

• Go to "Folder Options", open "View" tab and uncheck "Hide extensions for known file types". This will make it easier to find proper files in drivers you'll download soon.
  
  
• Close applications you don't need.
  If you have some pretty important data make backup.
  Driver updates never cause data loss, but backup it's never bad thing.
  
  
• Open link on Intel website where you get your .exe installer.

Step by step how-to for driver installation

Please note: you have to follow this guide exactly as this instruction said.
If you try to do that different way it's likely won't work and you'll stuck.

• Download the ZIP version of driver package.
  
• Extract the zip file somewhere easy to find, e.g your "Desktop".
  
  
• Go to Device Manager
  
• In "Display Adapters" find "Intel(R) HD Graphics"
  
• Right click on it and go to "Properties"
  Now new window should appear.
  
  
• Click "Driver" tab
  
• Then click "Update Driver..." button.
  A new window will appear.
  
  
• Now click on "Browse my computer for driver software"
  
• It's will show you next page.
  WARNING: DO NOT click on "Browse" here! Ignore this form!
  
  
• Click on "Let me pick from a list of device drivers on my computer"
  
• In this window click on "Have Disk..." button.
  A window pop's up to find the driver
  
  
• Navigate to the extracted driver folder
  
• Go to the "Graphics" sub-folder
  
• Click on the igdlh64.inf (or igdlh32.inf if you have 32-bit OS)
  It's should gone back to last window with only one driver to choose from
  WARNING: Name of INF file might be different!
  
  
• Select that only driver and click "Next.."
  Done
  
  
• If system offer to restart your PC I recommend to do that.

After you do that latest driver should be installed and working on your computer.

I have a problem! Can you help me?

There is two problems that happen most often:

1 - For some reason your ZIP unpacking software failed to unpack driver package properly.
To check this open directory with unpacked driver, and try to find "igdlh, igdlh64, igdlh32" files in "Graphics" directory. If you don't see this file most likely extraction failed. Try to use 7z[www.7-zip.org] or WinRar[www.rarlab.com] to unpack driver archive.

2 - You can't select .inf file in browser. This likely mean you ignored my warnings and didn't followed instruction, e.g didn't clicked on "Let me pick from a list of device drivers on my computer". Try again.

Should I use this instruction every time I need to update drivers?

No. Once you replaced laptop manufacturer drivers with generic one you'll able to update them using standard generic drivers *.exe installer from Intel website.
