AVLock Simple is a simple and powerful licensing component. It does not have forms of any kind, simply does the work and gives you the necessary features to retrieve the registration status and to register your application. The design of the registration interface is up to you. The way as you protect your program according to the registration status is up to you. In this way you will be able to implement all possible configurations for previous AVLock versions and much more.

A lot of new features has been added in this release mostly in order to add online licensing capabilities. A new set of php scripts called the Online License Manager (OLM) now allow you to manage the whole licensing cycle, namely to start the trial period, optionally extend it, purchase and activate the application, and finally to move the license to another computer if needed, includes an online utility -the control panel- to allow you to access to the remote database in order to view and edit the registration data. Also, allow to configure your application to be installed into a removable disk like a pen-drive, memory stick, etc.
