2024 TurboTax acivation

[user17574784251]

Computer activation issue.

I downloaded TurboTax 2024 onto my old win 10 computer in December 2024. I was able to successfully complete my 2014 income tax. Subsequently, during 2025, my old computer crashed several time making it necessary to reinstall Win 10 and various apps, including TurboTax 2024. Recently, this happened again. This time I decided to replace the Win 10 computer with a new Win 11 computer. All went well until I attempted to activate TurboTax 2024 so I could view last year’s return. I receive this message.

“All available activations for that code have been used.Error code: 603”

Is there a solution to this issue?
