On right number one. It is already a right. While some people think that the shrinkwrap license means that if you open it, you bought it, this is not exactly true. Because the ToS is not read before you pen the package, you have the right to a full refund if you do not agree. Just take it back to the store. They MUST refund your money, as long as you return everything and you do not have it installed on your computer.

Not sure if you were driving at something else here, but I thought I would mention this.
