There was a problem in the past if you installed the CD then tried to install by downloading to another computer. That is no longer a problem since there is no more CD and you have to download the program.
Since you now have to log into an Intuit Account all your downloads and licenses are listed there (even if you bought it from somewhere else) so if you need to download to install it again or install on another computer, even on the other operating system (Windows, Mac).
