Hello there, paul1234.

To get the validation code, you'll need to contact our Customer Care Team during support hours. They can pull up your account and provide you the validation code specific for you.

Aside from that, you can start a chat session with our representatives, too. You can use this link for reference: Contact QuickBooks Desktop support.

Once you have the validation code, you can already activate the program: Activate QuickBooks Desktop for Windows.

Let us know how this goes so we can further assist you. Have a great day!
