Step 6 – In the 'Specify Certificate Authority Response' window shown below, under 'File name containing the certificate authority's', click … to browse for your .cer certificate file that your CA sent and click 'Open'.
Step 7 – Next, enter a 'Friendly Name' for the certificate in the box provided in the window as shown in the image above. The friendly name is for internal reference only and will not appear in the certificate.
We recommend adding the CA’s name and the certificate expiration date at the end of your friendly name to help identify the correct certificate.
Step 8 – Click on ‘OK’ to install the SSL certificate to the server.
Step 9 – Typically, after completing the certificate wizard, IIS will start using the new certificate and a restart is not necessary. To test installation, use our SSL Checker Tool or visit the secured URL with a browser other than Internet Explorer.
If the server still continues to deploy the old certificate or your website is having problems loading via HTTPS, please shutdown and restart the web server.
