PURPOSE: To set the experience evaluation of a software product to be precise and to use an environment and data, which are accompanied by a trial even after they are formally introduced on a software trial management system. CONSTITUTION: When the trial of a free sample is started, it is always checked whether the trial period is expired or not (step 104). When the trial period is expired, prescribed function limitation is executed and the free sample is set to be impossible for practical use (step 112). When a user executes a countermeasure for releasing function limitation, all function limitations are released and continuous use on the software product is made possible (step 122). Thus, the user precisely experience-evaluates the function, the performance and the operability of the software product, formally introduces the software product and he can continuously use it as it is. |
