Generate a key for your customers and encode the sale date into the key.
Also, implement a RTC test in your software to make sure the user does
not change the system time (set time back).
And you may want to register also computer's ID (for example HDD and CPU
ID) to make sure the key is not used in multiple computers.

Hello,
I wonder what component would you guys use for such as a need:
I need to provide licenses for a product with 1 year of new version updates
beginning from each sale date. Then for a upgrade fee (smaller than the
retail price), I will let them update. Something advancedinstaller uses...
Best Regards,
SZ
