How to get the signer's company name from a memory signed file data?

I use the CryptQueryObject function to get HCRYPTMSG* phMsg.

The dwObjectType is CERT_QUERY_OBJECT_BLOB and the pvObject is a CERT_BLOB (set the memory data point and size) pointer. It can work in windows7, but has problem in Vista. In Vista, it will return error code 0x80092009 ("cannot find the requested object").

Any suggestions? Thanks all.
