How to Install an SSL/TLS Certificate In Microsoft IIS 8

The following instructions will guide you through the SSL installation process on Microsoft IIS 8 using a SSL certificate that only secures one domain name. If you have more than one server or device, you will need to install the certificate on each server or device you need to secure. If you still have not generated your certificate and completed the validation process, reference our CSR Generation Instructions and disregard the steps below.

What You’ll Need

1. Your server certificate

This is the certificate you received from the CA for your domain. You may have been sent this via email. If not, you can download it by visiting your Account Dashboard and clicking on your order.

2. Your intermediate certificates

These files allow the devices connecting to your server to identify the issuing CA. There may be more than one of these certificates. If you got your certificate in a ZIP folder, it should also contain the Intermediate certificate(s), which is sometimes referred to as a CA Bundle. If not, download the appropriate CA Bundle for your certificate.

3. Your private key

This file should be on your server, or in your possession if you generated your CSR from a free generator tool. On certain platforms, such as Microsoft IIS, the private key is not immediately visible to you but the server is keeping track of it.

Known Error Messages in IIS 8

Microsoft IIS 8 is known to generate error message: “Failed to remove the certificate.”

If you are certain this is the same server where you generated the CSR, then the error may be meaningless and the certificate may have correctly installed.
