The steps below will guide you through the process of installing the UAD software, registering your Apollo, and authorizing your UAD plug-ins. 

Important Note: A Windows 10 PC with Thunderbolt 3 built-in via USB-C and a qualified Thunderbolt 3 to Thunderbolt adapter are required to use Apollo via Thunderbolt with Windows 10. For details, see the Apollo Thunderbolt Windows Compatibility article.
 

1. Connect and power Apollo
   
   Before installing the UAD software, connect your Apollo to a Thunderbolt 3 enabled USB-C port on your PC via a Thunderbolt cable and qualified Thunderbolt 3 to Thunderbolt adapter, then power on the Apollo. 
   
   A "New Thunderbolt devices have been attached" message will appear when connecting your Apollo Twin to the computer for the first time. For details, see this article.
   
   
2. Download the UAD software
   
   Registration and authorization is managed by the UAD software. Visit www.uaudio.com/register to get the latest UAD software installer.
   
   
3. Install the UAD software
