    You can have a logic where in you decrypt/encrypt a string which is in registry into a date and compare it with the installation date and no of days used.Hope this might help...

    Thank you,
    Bhanu.

    Yup, u have to deal with registry setting.


  • jco2007

    That was an idea I had, too. But how do I access the registry and how can I edit it. Some Software-Products I know are easy to manipulate if they use the registry to remember the date of installation. Are there other possibilities Or how can I do it on a save way using the registry

     

    Thanks ...
