Installing a NIU Security Certificate for Internet Explorer

There are currently two NIU Security certificates being used by different web-based applications. Users are advised to install them both. This will prevent warning messages from being displayed as you use NIU web-based applications requiring authentication.

Since browsers do not share data, users must install the certificates into each browser application. For example, a certificate installed into Internet Explorer will not work for Mozilla Composer and vice-versa. Note that actual screens may be drawn differently or contain other information, depending on your operating system and the certificate being installed.

To install a NIU Security Certificate for Internet Explorer:

1. Download the appropriate NIU Security Certificate by selecting from the following:
   • NIUCA - This Security Certificate is primarily used by older (implemented before December 2003) web applications.
   • NIUCA2 - This Security Certificate is primarily used by newer (implemented after December 2003) web applications.
2. A File Download window will open.
3. On the File Download window, select "Open this file from its current location" and then select "OK."
   
4. The Certificate window will open. Select "Install Certificate..."
   
5. The Certificate Import Wizard will open. Select "Next."
   
6. In the Certificate Store screen, select "Place all certificates in the following store" and then select"Browse..."
   
7. At the "Select Certificate Store" window, select "Trusted Root Certification Authorities" and then select "OK."
   
8. At the Certificate Store screen, note that the "Certificate store:" prompt lists "Trusted Root Certification Authorities." Select "Next" to continue.
   
9. At the Completing the Certificate Import Wizard screen, select "Finish."
   
10. A Root Certificate Store confirmation box will appear. Select"Yes" to install the certificate.
    
11. The Certificate Import Wizard will notify you that "The import was successful." Select "OK" to finish.
    
12. Close and restart Internet Explorer
13. The security certificate is now installed. If necessary, return to step #1 and install any certificates that have not yet been installed.
