Hi. I have quickbooks online. I need my license no. and product no. so I will be able install quickbooks desktop

Helping out with getting your license and product number to install QuickBooks Desktop is my top priority, lillycarpetmanil. 

If you purchased QuickBooks Desktop from a retail store, the license and product numbers are given by them. You can also check the receipt page or confirmation email for these numbers. Just go to the Junk or Spam folders if you're unable to find it. 

Another way to locate your license or product number is by going to this link: https://emaillicense.quickbooks.com/app/qbdt/licensenumber. Then, choose either via business email or business phone. Once done, click the Find license and product number button.

Lastly, you can access the Customer Account Management Portal Site (CAMPS) web page. This allows you to manage all your QuickBooks Desktop products and locate your license/product information.

Here's how to find your product license:

1. Sign in to camps.intuit.com. Or learn more about signing in.
2. Find your app or subscription in the Products & Services list.
3. Select Details. Then, choose your QuickBooks product.

For more details about this one, check out this article: Manage your QuickBooks Desktop subscriptions and services. 

Once done, install QuickBooks Desktop and activate or register your software.

This will get you on the right track. Don't hesitate to leave a comment if you have any other questions about running your business in QuickBooks. You have a good one.
