How can I install trusted root certification authority using CAPICOM?

I'm using VB6 to install a certificate under Certificates (Local Computer) \ Trusted Root Certification Authorities. I'd like it to be silent, but if there's the usual warning message, that's OK.

I tried this code:

    Dim cc As New CAPICOM.Store
    Dim c As New Certificate
    c.Load "C:\Zap\cacert.crt"
    cc.Open CAPICOM_LOCAL_MACHINE_STORE, "Trusted Root Certification Authorities", CAPICOM_STORE_OPEN_READ_WRITE
    cc.Add c
    cc.Close


What this did was create ANOTHER folder called "Trusted Root Certification Authorities" containing a single certificate (the one I added). The real "Trusted Root Certification Authorities" folder didn't contain the certificate.

Any suggestions for how to install a Trusted Root Certification Authority using CAPICOM, preferably silently?

Thanks for your time,
