registration won't work

Hi Craig1957,

Welcome to QuickBooks Community. It's marvellous to see new members reaching out with their questions. Technology is in a state of perpetual change, and QuickBooks recognizes that and provides you with all the information you need to keep up. I can point you in the right direction with the steps for moving your QuickBooks from one computer to another.

Confirm that you've completed all the steps in this article: Move or reinstall QuickBooks Desktop to another computer. Here are a few other articles that you can review that can provide some insight: 

• Register QuickBooks Desktop using Intuit Account
• Download QuickBooks Desktop
• Activate QuickBooks Desktop for Windows

If you're still having trouble registering your product, I suggest reaching out to a support agent. You can find the contact information in this link: Intuit QuickBooks Desktop software support policies.

You can always reach back out if you require further assistance. Have a great weekend!
