validation code for simple start 2007%0D%0A

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.

Let us know if you need additional guidance. We're here to help.

You can use the trial version as a workaround. Another option, upgrade your data to QB Desktop 2020 or 2021 with a non subscription license.
