Hello,
For your kind information, a purchase code/license is for only using one active domain/sub-domain/directory/sub-directory. To activate the theme 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.
Also, the license does not support multisite or something similar.
Best Regards,
