Hello there, In321.

Let me route you to the correct support to get your validation code.

To get the code, you'll need to contact our Customer Care Team during support hours.

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.

Keep me posted whenever you need help in managing your files. Keep safe!
