Hi,


We recently purchased an EV certificate to sign our software kernel driver, however, when trying to load it in Windows 10 it fails with code 0x800B010C aka CERT_E_REVOKED - A certificate was explicitly revoked by its issuer.
We checked the driver with "signtool verify /v /all /pa" as suggested by our cert provider and everything is still valid and the cert provider also confirmed it didn't revoke our certificate.
We followed the instructions for https://docs.microsoft.com/en-us/windows-hardware/drivers/dashboard/attestation-signing-a-kernel-driver-for-public-release yet the driver is not loading

 

We've also tried contacting Microsoft's dev support but MS closed it down recently and they're not replying anymore...

 

Any help would be appreciated,

Thanks!
