How to find which activation code is used on which computer

Hi,

I have bought several licenses under the same user account. For each license I have an activation code, and I have used those codes for various desktops and laptops.
How can I retrieve the link between the activation code and the avast installation on an individual computer? Which code did I use on which computer?

Thanks if anyone can help me out,

Leo.
