I got exactly the same problem as yours. The installation went smoothly but it didn't ask for the license key and I wasn't able to activate the program. I then went to website turbotax.ca./activate. It asked me to enter the activate code (license key), which came in the email from Amazon, from which I bought the software. I entered the code but it kept getting rejected. I uninstalled the whole thing, re-installed it and this time the installation asked for the license key. I entered it and it got accepted. Done. My suggestion: uninstall and reinstall.
