In the Certificate Manager window, switch to the Authorities tab and click the "Import..." button.
Find the saved certificate file on the hard disk and click the "Open" button.
In the Downloading Certificate window it is necessary to select for what purposes you trust the certificate.
Select all of the checkboxes presented and click the "OK" button.
