Kernel driver code signing help

Thanks Maxim.

I verified that update KB3033929 is installed on the target computer.

I made some progress this morning. I had to manually add the “VeriSign Universal Root Certification Authority” which was required by the “Symantec SHA256 TimeStamping Signer - G1” to the target computer. I also had to add the “Symantec Class 3 Extended Validation Code Signing CA - G2” certificate. After that things started working OK.

I am a little confused, I thought buying and signing with the certificate we got from Symantec the proper certificates will be installed when installing the driver.
