doing a reinstall 2018 desktop pro

Thank you for posting here in the Community, @GREG126.

Let’s enter your product and license numbers in QuickBooks Desktop (QBDT) 2018 to get you back on track with your business.

Your QuickBooks product code and license number can be found in several ways. This helps us verify if we’re entering the correct numbers:

• If you bought QuickBooks Desktop from our website, you'd received an email with your purchase confirmation and product details.
• If you bought QuickBooks from a retail store, kindly look for the brightly colored sticker on the original CD envelope.

Otherwise, you’ll want to double-check it by logging into your Customer Account Management Portal Site (CAMPS). It allows you to view your license and product information in the Product and Services section.

You can read through these articles for more insights:

•  Use the Customer Account Management Portal Site (CAMPS)
• Add, edit, and remove an authorized user in My Account (CAMPS)

If you have any additional queries on installing QuickBooks, please let me know; I'll be more than delighted to assist you. Have a nice day!
