LockXLS adds copy protection features to your Excel workbook. It makes formulae and VBA code unavailable to customer, adds various registration options - generate hardware based Computer Code, create Activation Code to unlock workbook on customer's PC, customize messages shown to customer during registration. Locked workbook may have trial period and splash screen. Also it will be converted to application, which does not have any external dependencies and could be easily distributed.
You should not write a code which creates hardware dependent Computer Codes, registration interface and other features needed for distribution. All of them are provided to LockXLS, you should only select needed options in the project and enter your own captions.
We suggest you to review How it works page to see how protected file works on customer's PC. Examples page contains protected files which you can download and test on your PC.
What you get using LockXLS:
* Spreadsheet is protected with a:
o Hardware based Activation Code (workbook will be locked to specific PC)
o Activation Code, bound to USB flash drive. This allows to control how many copied are launched on customer's PCs.
o Serial Number
o Trial period
o Password
* Create rental files using LockXLS. Hardware based Activation Code will unlock spreadsheet only to specified period of time.
* Limit evaluation and license by count of openings of protected document.
* On-line activation. LockXLS setup includes keygen applications for Linux and Windows, which could be used on your website. Also you can provide URL for on-line activation.
