AppPatrol is a copy protection system that offers robust application protection and feature-laden capabilities.

Much like you, we needed a way to allow customers to fully utilize our products during a trial period, but require the purchase of the product with continued use.

We have experience with many of the tools available by software vendors. We've tried software locks. We've tried hardware locks. We've tried the honor system. The shortcomings of all these methods gave rise to the necessity of our own copy protection system.

We like it so much, that we decided to make it available to our fellow developers.

Here are some key features of "AppPatrol":

· Option Enabling – you can provide your customers with a registration number that will contain information activated up to 24 premium portions of your software. If a customer purchases optional features at a later date, a new registration number can be sent (while maintaining the same lock type) that can activate those features. Any combination of optional features can be enabled.
· Application Expiration – a registered application can be configured to expire at the date of your choosing. The number of days remaining is available for your use (warnings, etc).
· File validation – An optional ActiveX DLL called AppPatrolUtils.dll can be shipped with your product. By calling this dll, you can ensure the AppPtrl.dll file on a user system has not been modified in any way.
