If you would like to activate the extension for more than one website or store in your admin panel of Magento®, you need to select the necessary number of domains in "I have one Installation of Magento® with ..." field and buy the license. If you have already bought the license for one domain, you can purchase additional domains in your GoMage account.
If you have several websites installed on separate Installations of Magento® YOU MUST buy a separate license for each website.
Where can I find the information about websites in my Magento®?
Log in to your Admin Panel of Magento® and go to System → Manage Stores. In the first column you will see how many websites there are in your Magento®.

Separate Installations of Magento®
Separate Installations of Magento® can be located on the same server or on different servers.
For each installation of Magento® YOU MUST buy a new license if you want to use GoMage extensions there.
