Installing a Primary Certificate in IIS7
Open IIS7 and under ‘Connections,’ select your server’s Hostname and in the center menu, in the IIS section, double-click the ‘Server Certificates’ icon.
In the ‘Actions’ menu, click ‘Complete Certificate Request’ to open the Complete Request Certificate wizard.
Under ‘File name containing the certification authority’s response,’ click ‘…’ to browse to the certificate file that you downloaded, select the file, and then, click ‘Open.’ Next, in the ‘Friendly name’ box, enter a friendly name for the certificate. The friendly name is not part of the certificate; instead, it is used to identify the certificate. To install the SSL Certificate to the server, click ‘OK.’

A certificate request must be completed on the computer where it was created.” You may also receive a message stating: “ASN1 bad tag value met”.

In the ‘Add Site Bindings’ window, enter the following information and then, click ‘OK.’
