After 3 weeks of frustration, last week Comodo finally sent a certificate
which they revoked a day later as they wanted me to send the same email
address as the original was issued. So I did that, backed up my key and
attempted to install the newer certificate but it has failed with the
attached errors. I am using the same pc and OS to order the certificate and
install. Clearly something is wrong. Is it possible to remove all traces of
Comodo certificates and just install the latest without error?
Thanks
