ABSTRACT:
A method is provided to permit copies of software products to be installed on systems, with a predetermined delay before commencement of a designated test period. The predetermined delay provides for a cumulative elapsed time, beginning with the installation of the software product to be evaluated during the designated test period, to allow for miscellaneous starts of the computer system prior to productive use for the purpose of evaluation during the user trial period. The miscellaneous starts may be associated with software product installation procedures during preload activities, attachment of devices and/or adapters to tailor the system to a particular user configuration, or to otherwise "boot" or check the system prior to productive use.
