Abstract
A method for controlling access to a product includes receiving a request for a product, generating a license string for the product, and transmitting that license string to a user of the product. The license string is generated substantially at the time a request is received. A corresponding system is also described. In some embodiments the product functions for a trial period before requiring input of the license string. License strings may be generated that extend the trial period.
