"The problem is, in the past when installing from a CD yiu were required to log into your TurboTax account (or create a new account if you did not have one). "
I've used TurboTax via disk from Costco for many years (since at least 2003), and I have NEVER had to log into my account in order to install it on my computers. In fact, it always gives me the option to register it later if I wish and continue without registering it, though I do at some point.
In fact, the only reason I had to set up an account with them was to look here in the Community Forums for some answers to questions and to fill out a survey for them.
