LockXLS adds copy protection features to your Excel workbook. It makes formulas and VBA code unavailable to your customers, adds various registration options--generates hardware based Computer Code, creates Activation Code to unlock the workbook on your customer's PC, customizes the messages shown to customers during registration. The locked workbook may have a trial period and a splash screen. Also it will be converted to an application, which runs on Excel but has no other external dependencies making it easy to distribute. There is no need for you to write a code which creates hardware dependent Computer Codes, registration interface and other features needed for distribution. All of them are provided by LockXLS, you should only select only the needed options in the project and enter your own messages.
