Hi, vagiles118. 

I want to ensure that you'll be able to activate QuickBooks Desktop.

When installing QuickBooks, you'll need to make sure that you've downloaded the right version that suits your license number and product number. An incorrect version may result in the error that you received.

First, use this tool to verify the code: Locate your License or Product Number.

If you get the same error, download the QuickBooks Tools Hub and run a Quick Fix to close any open background processes QuickBooks uses.

1. Open the QuickBooks Tool Hub,
2. Then select Installation Issues.
3. Select QuickBooks Install Diagnostic Tool.
4. Let the tool run. It can take up to 20 minutes.
5. When the tool finishes, restart your computer and start QuickBooks Desktop.
6. Open your data file and try to activate it.

If the issue still persists, I encourage you to get in touch with our Care Support Team. This way, they can verify if the code matches your QuickBooks' license number. 

Here's how:

1. Open QuickBooks.
2. Go to Help, then select QuickBooks Desktop Help.
3. Select Contact Us.
4. Give a brief description of your issue, then select Let's talk, and then choose a way to connect. Phone support may be limited due to volume.

Reach out to us during our operations hours. You will see it here: Support hours and type.
