Hi there, @Juma22. I'd be glad to help you with your validation code issue in QuickBooks Desktop (QBDT).
Before that, please know that we want to protect your account. If you noticed, the license number was removed for security purposes.
Upon checking the screenshot you've provided, I don't see any error messages but only the need to enter the code. The validation code is a unique key that is given to you when you buy the QuickBooks Desktop product.
If you buy the product online then you get an email regarding this key that helps you in registration and activate your account in QuickBooks. If you didn't receive an email, you'll want to contact our phone support since they have the necessary tools to generate validation codes and activate your QuickBooks. You may follow the steps provided by ReymondO above on how to contact them.
Please check our available hours before contacting them to ensure we address your concern timely.
Moreover, if you're receiving any error messages after you subscribe or sync your data in QuickBooks Desktop, here's an article that provides steps on how to fix them: Fix activation, license, and product numbers issues.
I'll be here to help if you have any questions or concerns. Take care always.
