-
-
11. The method of claim 5 further comprising:
-
recovering from said token an indicium of a second information product and an indicium of when the authorization for said second information product expires; and
installing said second information product onto said computer when said second candidate authorization code matches said second known authorization code and said indicium of when the authorization for said second information product expires has not expired.

-
17. A method comprising:
-
reading an encrypted token from a computer;
decrypting said encrypted token with a string, T, as the key to recover a token that comprises an indicium of a first information product;
modifying said token to comprise an indicium of a second information product;
encrypting said token with said string, T, as the key to create a newly encrypted token; and
