Don't lose revenue to software piracy - get ZQure today!

ZQure (pronounced "zee-cure") is a software licensing and protection tool for .NET software developers that helps developers easily protect their desktop applications and libraries from being distributed and used unlawfully.

Essentially, developers issue each purchaser of their software with a licence key generated by ZQure. The licence key is used to activate the user’s copy of the software. In this way, a developer might distribute a “crippled”, but free, evaluation version of a software product for evaluation by potential users. Users can then opt to purchase a licence key to immediately activate the full functionality of the product. Alternatively, the product can be made completely unusable until it is activated with a licence key. Licence keys can optionally be made to expire after a period of time creating the possibility of enforcing the re-licensing of a product on a recurring basis.


ZQure offers a host of benefits, including the following:

  • It helps prevent illegal distribution of your software by preventing execution of your software if it has been copied from another computer.
  • It features exceptionally strong multi-layer protection to ensue that only legally licensed users can access the protected software applications based on electronic security keys.
  • It offers quick and easy licence key generation.
  • It offers an easy-to-use licence key manager.
  • It offers simple and straightforward software-based product activation.
  • It is entirely software based, requiring no hardware dongles, special disks or other external tools.
  • It provides software developers full control of their licence creation and distribution.
  • It offers highly flexible software licence restrictions. You can:
    • Optionally restrict key usage on a per computer basis.
    • Optionally restrict key usage on a per software product basis.
    • Optionally impose a licence key expiry date.
  • It includes tamper detection to respond to software piracy.
  • There are no run-time licenses or fees!
