Prior to installing the Horizon Composer software, restore the RSA key container that was backed up in the section Backing up the Horizon Composer SSL certificates. The following steps outline the full restore process:

1. Copy the keys.xml backup file to a location on the new Horizon Composer host server. In our example, the file has been placed within the folder from which we will be executing the restore command.
2. From the Command Prompt on the new Horizon Composer host server, navigate to the c:WindowsMicrosoft.NETFrameworkv4.0xxxxx directory.

3. Execute the following command to import the Horizon Composer RSA key container. A screenshot that shows the expected output if the command was successful is provided after the command:

         aspnet_regiis -pi "SviKeyContainer" "keys.xml" -exp 

4. Reinstall Horizon Composer using the steps provided in the section Installing Horizon Composer. Since this is a new server, Horizon Composer will note that no SSL certificates are available and will create a new one.

Horizon Composer is now ready to be linked to the Horizon Connection server using the steps provided in the Configuring Horizon Composer section. If only Composer was restored, and the link between the Connection Servers and Composer is already present, you will need to re-verify the SSL certificate as described starting with step 5 of Configuring Horizon Composer.
