Change QuickBooks Desktop product number and/or license number without uninstall or reinstall

You may need to change the license and/or product number of QuickBooks Desktop for one of the following reasons:

  • It was installed with the wrong license number and / or product code
  • The amount of users are inaccurate, this can be due to using the single user license for installation instead of the correct Multi-User license. Once the license and product information in QuickBooks is accurate, the number of users will also be accurate.

    • If you do not restart the computer, The program will still deliver the incorrect license number to the server when you access the company file.
