Hello adrian,
For your kind information, a purchase code/license is for only using one active WordPress installation in a domain/sub-domain/directory/sub-directory. To activate the theme/plugin on a new domain/sub-domain/directory/sub-directory, you need to deactivate the purchase code/license from the existing domain/sub-domain/directory/sub-directory where it is installed now or you could buy another license to use the theme separately in a separate domain/sub-domain/directory/sub-directory.
There is an option to activate the plugin on a new domain/sub-domain/directory/sub-directory, you need to deactivate the purchase code/license from the existing domain/sub-domain/directory/sub-directory where it is installed now.
Best Regards,
