I’m trying to get some drivers signed to use on Vista 64-bit, but from Microsoft’s webpage, it doesn’t seem like my certificate signed by UTN-USERFirst-Object certificate is on Microsoft’s Root Authority Cross-Certificate list.

Is there some way I can use my existing certificate to sign drivers for 64-bit Vista?
Thanks!
