Cisco VPN client certificate import

Hi guys,

I have the task of renewing a remote users certificate which is about to expire. I have submitted an offline base64 file request to a Microsoft CA. I've issued the cert and tried exporting from the MS CA as DER / Base64 .cer but they always import into the Cisco VPN client as "RA" and not "Cisco Store". Any how I get the certificate to import into the Cisco Store?

Thanks

Jack
