Single DLL signing not working in Windows 8 (worked in 7) RRS feed

  • Question

  • Hello.

    I have an active Kernel Code Signing certificate purchased from DigiCert.

    I'm signing a single sys file using sightool

    signtool.exe sign /n "---my cert---" /ac "DigiCert High Assurance EV Root CA" /t http://timestamp.digicert.com mysys.sys

    The driver is signed, I can see digital signatures, but windows 8.1 rejects (windows 7 allows) it and doesn't allow installation due to "no signature".

    Please advise me on what I'm doing wrong.

    Thank you,

    Oleg.
