Abstract: In one embodiment, a method includes receiving a request to remove one or more limitations imposed on a full-featured base application executing on a client computer. The method further includes creating a license package. The license package includes a first layer and a second layer separately encrypted therein. The second layer includes a license key operable to be consumed by the full-featured base application to remove the one or more limitations. The first layer comprises information sufficient to identify the license key. In addition, the method includes encapsulating the license package into a file having a file-type association with the full-featured base application. Further, the method includes transmitting the file to the client computer. The method also includes interacting with the full-featured base application to allow decryption of the first layer and the second layer so that the license key can be applied.
