AVLock Gold is a development tool that allows you to transform a .NET or Delphi application into a trial with minimum effort. The application will add the required code in your program and convert it without damaging its functions.
All the operations are performed from the same interface which shortens the time required for creating a trial from a fully functional app. You can also define keys for certain users that can use the program for a limited period of time.
Note: The application is only free for non-commercial purposes unless you purchase a license.
