Welcome to the QuickBooks Community, @Moatag.
Let's fix the incorrect license/product number errors by performing some troubleshooting steps. This way, you can install your QuickBooks Desktop Pro 2014 successfully.
You'll want to make sure the license number and product code match. To check if you're using the correct license/product numbers, you can review your purchase confirmation email for your license number and product code if you bought QuickBooks Desktop from our website.
However, if you bought QuickBooks from a retail store, look for the sticker on the original CD envelope.
If you can't find them, you can sign in to your Customer Account Management Portal (CAMPS) to get them.
If you still can't see them, I recommend contacting our QuickBooks Support Team. This way, they can look into your account in a secure environment and give you the license/product numbers.
Just in case you want to manage your QuickBooks Desktop subscription and services, you can check out this article for more guidance: Manage your QuickBooks Desktop subscriptions and services.
Come back to this post if you have other concerns or follow-up questions about installing QBDT. I'll be around to provide further assistance.
