Hello there, saqha.

As much as I'd love to help you, but any concerns related to the validation code are handled by our QuickBooks Support Team. I'll ensure you'll be routed to the right person to assist you further on this so you can load Pro 2013 on a new laptop efficiently.

I can see that you've already reached our QuickBooks chat Support. However, I still recommend contacting our QuickBooks Phone Team. They're the best support group for such inquiries as they can request account information. This way, they can provide you with the validation code based on the details being recorded on their end.

In addition, you can also follow the steps shared above on how you can retrieve your validation code if you have registered your QuickBooks software with Intuit. 

On the other hand, please note that the QBDT 2013 version has already been discontinued. You will not receive the most recent important security fixes and updates. If you need to continue using this program with proper functionality, you may upgrade to a newer version. You can refer to this article to see the process: Upgrade QuickBooks Desktop Pro, Premier, or Enterprise.

Feel free to post again or comment if you have clarifications about the validation code or upgrading your QBDT, saqha. I'm always around to assist you further.
