# Do I have to purchase ThemeWare® again for another domain?

Licences of extensions are valid for the domain of your main shop (= licence domain) respectively your Shopware installation. You can use extensions for all Sales Channels (e.g. subdomains) in the same installation.

Accordingly, additional licenses are required for a further Shopware installation.
