Welcome to the Community forum, Bruno. Because QuickBooks Desktop 2007 (QBDT) has long been discontinued, validation codes for transferring it to a new device are unavailable. It is best to keep using it on your current workstation to ensure continued access.
If you’d like to stay up to date, you may consider upgrading to a supported version of QBDT to keep your business running smoothly.
