Importing a PFX File onto Windows IIS 7.x, 8.x, or 10.x

Step 1: Open IIS Manager

Click ‘Start‘ >> ‘Control Panel >> ‘Administrative Tools‘ >> then finally, ‘Internet Information Services (IIS) Manager‘.

Step 2: Select the Server You Wish to Install to

On the left is the ‘Connections‘ menu, select the server name you wish to install the pfx file on. This will open a menu in the middle of IIS Manager.

Step 3: Navigate to Server Certificates

From this middle menu, select ‘Server Certificates’ which is listed under ‘Security‘.

Step 4: Import the PFX File

On the right, a new menu will appear. Click the option ‘Import‘.

Step 5: Select your PFX File

Click the browse icon and select your PFX file.
Include your password if you created one during creation of the PFX file and click ‘OK

Selecting your PFX in the 'Import Certificate Window' of IIS and entering a password.

Close and reopen Internet Information Services (IIS) Manager to refresh your SSL Certificate Installations. Your new SSL certificate should be available in your list of installed SSL Certificates.

If, however, the SSL Certificate is still not present you may need to reissue your SSL Certificate. You will need to create a new Certificate Signing Request and then reissue the SSL Certificate.

Step 6: Binding the SSL Certificate

Return to the ‘Connections‘ menu from earlier and expand the server name where you installed the SSL Certificate. Expand ‘Sites‘ and select the site you are securing. Then in the ‘Actions‘ menu, select ‘Bindings…‘.

In the ‘Site Bindings‘ window, click ‘Add‘.

In the ‘Add Site Bindings‘ window, select the following options:

Type:In the drop-down list, select https.
IP address:In the drop-down list, select the IP address of the site or select All Unassigned.
Port:Type port 443. The port over which traffic is secure by SSL is port 443.
SSL certificate:In the drop-down list, select your new SSL certificate (e.g., yourdomain.com).
Adding Site bindings by selecting the 'Type', 'IP Address', 'Port', and 'SSL Certificate' options and entering the necessary details.

If you are using a Multi Domain/UCC SSL Certificate you may need to do this multiple times by specifying the Host Name (Domain Name) for each Domain hosted on this server that is listed on the SSL Certificate.

Select ‘OK‘.

Your SSL Certificate is now successfully installed.
