many Software makers alow for you to install their software on 2 personaly owned computers but the software is to be used only on one computer at a time. For example, Adobe Photo Shop and MS office both go out and look for other systems on your network that are running the same app with the same serial number. It wont open if that is found to be true. Now, I'm not sure if Adobe and MS are companies like the ones I was talking about but, they are, I would agree with their logic.
