AVLockGoldAVLOCK GOLD v5.3.3 For Delphi 4, 5, 6, 7, 2005, 2006. VCL, .NET, ActiveX. This new version greatly simplifies the creation of applications trials. A new utility, AVLockManager has been added centralizing all tasks implicated in the process, so it becomes a really professional suite for protecting your application in an easy and simple way.

The security aspect has been highly improved:

· The "encryptionkey" string has been added, used to generate the encryption key (128 bytes length) used with the Rijndael algorithm. In the previous version 4.x the AppID number (dword) was used to generate this key.

· Modules now have a "Moule ID" field asociated. Then, you may to change this value for a new improved version in order to disable the module and force so the user to pay again for this module.
· Related to the previous point as been added the "RestartModulesAsTrial" property; if True the modules with the "ModuleID" changed initiates a trial period otherwise it becomes disabled.
· The "TrialIncludeModules" property has been added to determine what to does with modules while the trial status. If True all modules are enabled while the trial period otherwise these are disabled.

NEW in v5.3

The InstallCode has been extended to 13 characters length in order to hold information about the machine numbers CPU ID, BIOS SN and HD SN, so when the user ask for an new registration key affirming that your machine was damaged, then you are able to determine if the new installCode received from the user come from the same computer or not and which part of the machine was changed.

In the user form in the AVLockManager utility has been added a new feature "InstallCode report", so when you receive a new InstallCode you can see a comparative report displaying old and new values for the CPU ID, BIOS SN and HD SN.

Several events have been added in order to improve the user-component communication and enhance the component customization, especially when you define your own registration form. These events are the following: OnStartError, BeforeRegisterKey, AfterRegisterKey, AfterRegisterAll, OnRegularRegistration, OnRequestName, OnMoveReg and AfterRegMoved. See in the Demo3 program how to use them.

In the registration form, the "Another way" registration option was changed to the "Print order form" feature, so you may give to your users the option to print a registration form in order to be posted to you.

NEW in v5.2
