Windows 10: the driver cannot be installed because it is either not digitally signed or not signed in...

Hello, I am trying to print a page from my new Lenovo flex 5.

I added my printer brother mfc-j430w but it says the driver is unavailable, I also tried to update the driver from device manager but I get the line mentioned above in the subject.

:)

 

Turn off Driver signing

I cant install ATI Tool because Vista wants a digitally signed driver. How can I turn of this setting.

Thanks

 

Digitally signed driver not verified by Windows

This is a typical error you get if vendors are still only cross-signing their drivers.

Note: Please provide your exact Windows Version next time!

However, I'm assuming that your Windows 10 version is at least 1607 (aka Redstone 1, Anniversary Update) and you have Secure Boot enabled.

If my assumption is true, this driver won't work.

I've extracted the .sys and .cat files from the installer package and verified that these drivers do not have a Microsoft signature:





Since Windows 10 version 1607, a tightened kernel driver certification is enforced. The new rule is that all Windows 10 drivers must be digitally signed by Microsoft, no more cross signing! Kernel driver developers must now use an Extended Validation (EV) code signing certificate and submit their drivers to the Windows Hardware Developer Center Dashboard Portal where the drivers will be signed by Microsoft.

In that case you would see a signature like this:

How do I allow cross-signed kernel drivers in Windows 10 version 1607 with secure boot enabled?

What are your options now?

• Ask the vendor to provide a Microsoft-signed driver (should be taken for granted actually)
  
• Disable driver verification (as you've already discovered)
  
• Disable Secure Boot
  

 

Getting "a digitally signed driver is required"

Hi Thomas,

This error can occur if there is a driver attempting to be installed on the system that was not signed by Microsoft digitally. Driver digital signatures help verify the integrity of the driver packages. To avoid this error, you need to disable the driver
signature enforcement. Follow the steps below:

• Press and hold the Shift key then click Restart button.
• Choose Troubleshoot, then select Advanced options.
  
• Select Startup Settings and click Restart.
  
• Once the computer restarts, you'll see a list of options. Press F7 to select
  Disable driver signature.
• Computer will now restart. Once done, check if the same error will occur.

Let us know the outcome so we can provide further assistance.
