1Password 7 for Windows license download

Hi,

I've purchased a windows license for 1password7 (yes, I know, that is very old) however, I need to install a new PC. The email which gave me the license gives the license as a download link. This used to go via fastspring.com However, the link does not work anymore. 

Any ideas on how I get to my license. I still have access to a laptop with a working 1password 7 which shows my license details. Is there a location where I can find the .onepassword7-license-win file to copy it to the other laptop maybe?

Regards,

Richard
