Step 4 – As shown in the image below, click on the option of 'Process the pending request and install the certificate', from the 'IIS Certificate Wizard' window.
Step 5 – Now, browse for your SSL certificate and locate 'your_domain_name.cer'. Then, click on 'Next' and follow the rest of the steps until finished.
Step 6 – 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.
