Abstract
Digital product execution control as disclosed contemplates production of a final version of a digital product and subsequently imposing execution control on that digital product. The manufacturer of the original digital product need not incorporate execution control features into the final version of the product. Execution control programming attaches to an executable file of the digital product to create a controlled executable file. Upon loading and execution of the controlled executable file, the resulting operating environment is insufficient for the original executable file, and control programming determines whether or not execution will be allowed. If allowed, control programming creates the necessary operating environment for the digital product, i.e., as would be provided by the operating system if loaded normally, and allows execution of the digital product only under controlled conditions, e.g., such as under an evaluation use of the digital product.
