QuickBooks Activation Not Working is a time-consuming issue and requires immediate remediation to start your work in QuickBooks. A wrong QuickBooks License and product number can also be the reason for QuickBooks Activation Not Working.

In this blog, we will list methods that can update your license and product information in QuickBooks without doing any QuickBooks install or reinstall.

Modify/Change License number Only(Windows Users)

Go to the QuickBooks ‘Help’ menu and choose‘Manage My License’ option.

Click on ‘Change My License Number’

Now Enter the ‘New License number’ and click NEXT and Finish.

Now Restart Computer

Note: If you didn’t restart the computer, then the program will deliver the incorrect product info to the server at the time when you access the company file. In case you are on the multi-user mode networked with several seats, then QuickBooks will give you the error saying ‘You have exceeded the maximum number of users who can access the Company file at a time.’
