Most of our items, such as themes, code, graphics, 3D models, and flash assets, are covered by our Standard Licenses.
If your end product, which includes the item you purchased, is free for the end user, then you should choose the Regular License.
However, if the end user has to pay to use the end product that includes the item you purchased, then you'll need the Extended License.
Note: If you use the Regular License, you are allowed to use the purchased code for one domain only. Therefore, if you wish to use it for another domain, you will need to remove the active purchase code from the previous domain.
