Installing Turbotax Deluxe 2024 on a 2nd computer

[Gary143]

I installed my Turbotax Deluxe 2024 on my old Windows 10 computer.  I now bought a new Windows 11 computer and cannot seem to activate the license on the new computer.  I get "The license code you entered is not valid. Error code: 605"

I am logged into my Intuit account when I install and attempt to activate.

If your license code worked on your Windows 10 computer, and you haven't used it five times yet, try this:
