    Hello,

    You can use any general method. There are no specific facilities in SDK to do this. Check on Google, you'll find many methods.

    Easiest is to store the installation date somewhere in the registry in encrypted form, and than checking the number of days elapsed against that date.

    Though, do keep in mind that nothing will be fool proof, and somebody really hell-bent on breaking will always be able to find out a way.

    Regards,
