So I got the same message. Installed on a computer via the CD, but wanted to install on a computer without a CD drive so went to download it. Called the TurboTax help line which was a waste of time. She finally asked for the license code, but said it came up as invalid. Here is what I found out:
1) if you buy the CD, DOWNLOAD it rather than installing from the CD if you can. When you install from the CD it doesn't ask for any TurboTax account info so it doesn't associate it to you.
2) If you only can install from a CD, you can install it on other computers (up to 5) with the license code, but you can NEVER download it if you installed from the CD first.
3) I successfully installed on a second computer with a CD, but couldn't use the download to do it.
I have to remember this next year as I always get a CD.
