You own a copy of the software, and when you install it, you are presented with limitations which, if you agree to them, are binding only in the context of using the software. Outside those boundaries, any limitations do not apply. You can restrict your users by making them agree that your software cannot be used for commercial purposes, for example, but you can't make them agree to terms that apply when they are not using the software, such as a restriction from reselling the installation discs after they have stopped using it. It's when they use the software after having resold the discs that they might be said to be infringing a usage contract.
