This project is read-only.

How It's Work

You need to generate all your keys using Visual Studio GUID generator and put those in a database. Dot License uses Access Database to store and retrieve information. When client request for Activate using one GUID key, system will validate key from a web server and store a BASE64 string to Windows Registry which is encrypted with Processor ID and GUID key. So that, client can not run same application from different PC using single key.

License Form

Activate Form

Add Activate Form in your Windows Application. All fields are required to activate. Activation Code is the GUID key which you need to provide your client and that is unique. In Activate Form you see Processor ID which you must hide when distribute your product. Processor ID will be generated automatically on Form Load event.

Table Apps
