That means a FacebookTab module license holder have free access for all future versions of the module for X-Cart v4.x

Unfortunately, we are not sure about X-Cart5/LC3 as it is a new platform and there may be different license terms and conditions.

If you can install X-Cart you will be able install the module, too.

Thank you for the suggestion.

Licensing for the module is pretty standard - one module license for one X-Cart powered shop. However, the same module can show products from the same X-Cart on multiple Facebook community/business pages.
