Pay special attention to the value you provide in the Enter the name of a file in which to store the certificate request field and click OK.
A message is displayed that informs you where the file that contains your new certificate request is located. The message tells you to send that new certificate request file to your external certificate authority.

The external certificate authority signs your new certificate request and sends back your new certificate.

Search the lists of CA Certificates, select the one(s) for the external certificate authority that signed your new certificate request, and click OK.
If the lists of CA Certificates do not contain the one(s) for the external certificate authority that signed your new certificate request, ask your external certificate authority to send their signer certificate.

Once you have the signer certificate for the external certificate authority that signed your new certificate request, complete the following tasks:
Select Personal Certificates and click Receive.
Provide the File Name and Location values of the file that contains your new certificate and click OK.
Select the certificate with the default label and click Rename.
