clip_image049Note
If this option is not available, the certificate has been created without the option to export the private key. In this scenario, you cannot export the certificate in the required format. You must reconfigure the certificate template to allow the private key to be exported, and then request the certificate again.

4. On the Export File Format page, ensure that the option Personal Information Exchange – PKCS #12 (.PFX) is selected. Click Next.
