This guide explains how to add a certificate to a computer in simple steps. Follow these instructions carefully to ensure the certificate is installed correctly.

What You’ll Need

• A computer with Windows.

• Windows Administration Rights (You will need to ask your IT Team for assistance)

• The name of the computer you’re working on.

• The certificate from the HESSDA server (provided with your software).

Step-by-Step Instructions

1. Open the Management Console

   • Click the Start button (Windows icon) on your computer.

   • Type MMC in the search bar and press Enter.

   • A window called “Console1” will open.

2. Add the Certificates Tool

   • In the Console1 window, click File at the top, then select Add or Remove Snap-in.

   • Find Certificates in the list, double-click it, or select it and click Add.

3. Choose Your User Account

   • A window will pop up. Select My User Account and click Finish.

   • This adds the certificate tool for your account.

4. Add the Computer Account

   • Back in the Snap-in window, double-click Certificates again.

   • This time, choose Computer Account and click Next.

   • Select Another Computer, type the name of the computer you’re working on, and click Finish.

5. Find the HESSDA Server Certificate

   • In the Console1 window, you’ll see a list on the left. Click the arrows to expand Console Root until you find Trusted Root Certification Authorities and then Certificates.

   • On the right side, sort the certificates by Expiry Date (click the column header).

   • Look for the HESSDA server certificate at the top (it has a 100-year expiry date).

   • Right-click the HESSDA certificate and select Copy. (Important: Do NOT select Cut or Delete!)

6. Paste the Certificate to the Client Computer

   • Still in the Console1 window, find the Certificates folder under Trusted Root Certification Authorities for the Computer Account (the client machine you added in Step 4).

   • Right-click in the right pane and select Paste to add the copied certificate.

Done!

You’ve now installed the certificate on the workstation.
