A computer implemented method, for multiple-mode software license enforcement on a client, including encoding in the software at least one predetermined event that occurs prior to a validation of the software program and encoding it with different functional states. The software's resulting modification may be of reduced or increased functionality or both reduced and increased functionality. The predetermined events may be the elapsing of a predetermined length of time, the entry of a valid registration key or an act of validating. Each of these events may take place a multiple number of times.
