Microsoft IIS 5.x and 6.x Certificate Installation

To proceed with Microsoft IIS 5.x and 6.x certificate installation, you need a copy of your SSL certificate. You would receive your certificate from us, a file typically named your_domain_com.crt, as well as the Certificate Authority (CA) bundle file containing the intermediate certificates, typically named either dv_chain.txt, ov_chain.txt, or ev_chain.txt and downloadable from your SSL control panel.

Certificate Installation on Microsoft IIS 5.x and 6.x

1. Open your Control Panel by clicking the Start icon on your computer and search for Control Panel.
2. Open your Administrative Tools.

   Note: If you cannot find your Administrative Tools within the Control Panel, go to the Start Menu, then All Programs.

3. Double-click the Internet Services Manager or Internet Information Services option.
4. Right-click the website, then choose Properties.
   
    
5. Go to the Directory Security tab, then click the Server Certificate button.
   
    
6. The IIS Certificate Wizard will open. Click on the Process the pending request and install the certificate radio button, then hit Next.
   
    
7. Browse to your SSL Certificate file, then hit Next.
8. Double-check the information on the screen to ensure you are installing the correct certificate, then click Next.
9. Click Next again. 

The certificate should now work! Note that it can sometimes require a restart of IIS to bring the new certificate into effect.

Note: To install Root or Intermediate Certificates, check out Sectigo's support document.
