We have a file system driver which signed with Globalsign certificate and Windows Hardware center. Driver has been loaded successfully in Win10 , Win 8 and Win7. But it failed to load in Win 8.1 with error message box "A digitally signed driver is required".

Can you help to resolve this issue?

Was this attestation signed, or signed through the full WHQL process?  Do you use the same driver binary for all versions?  Does the driver install correctly on 8.1, or does the failure happen at install time?

We have signed our driver with EV code signing certificate from global sign. Not sure why we are still having the issue. Any idea why we are seeing this errors in Windows 7 and 8?
