I am currently looking for Teaching Textbooks Algebra II for Rachael next year. While searching, I came across a post on some board somewhere that says you can only install it TWO TIMES. In other words, I buy it new and install it on my machine and use it. The next year, I sell/give it to a friend who then installs it on HER machine and uses it. But when she sells it to a THIRD person, it WILL NOT install on that machne! The post said that you can call in requesting some code, but ONLY if you can prove you bought it from the company to begin with. Now, I don't know if this is true, but it REALLY bothers me! First of all, it means I cannot buy it used, just in case I'm not buying from an original user. And, what's more, I don't think it's any of their business if we sell/give away a product we're done using! So has anyone else heard this, or have any idea how to find out if it's true?
