Cross certification certificate for Vista 64-bit code signing?

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!

Hi,

We are working to get into the Vista program, but at this time Vista signing is not supported.

I am sure we will announce it when we are successful.
