Purchased QB 2020 a few days ago, with 1 license for 2 users. when I try to log in, QB says I need to upgrade. How do I do this?

All you need is the appropriate set of procedures, and you can have it ready for multi-user in 15 minutes. You must do the following steps to the word:

1. To begin, you must log in to the server, which requires a valid User ID and Password.
2. After completing the login procedure, click on the "Start" menu on the desktop screen.
3. Select "Run" and navigate to "appwiz.cpl." "Appwiz.cpl" is the component of the Control Panel that allows you to add and delete apps. As a result, selecting this option will launch the "Add or Remove Programs" window.
4. Now, after you've gotten the hang of it, let's get started right away! Next, right-click on the QuickBooks version that needs to be upgraded and select Upgrade. Then, from the drop-down menu, pick the "Uninstall" option.
5. Upgrade your QuickBooks license to a multi-user license.
6. After that, navigate to My Computer. Navigate to the C drive. Select the Documents and Settings option. Then, click All Users, then Application Data, then QuickBooks, which reveals the four-digit version year.
7. To guarantee a seamless installation, erase all of the contents of the installation folder that has opened in front of you. In the true sense, deletion occurs after the conclusion of this stage.
8. Reinstall the QuickBooks program using the proper license code and product code. You must repeat the identical installation method that you used the first time you installed QuickBooks. As a result, you won't have to worry about this because you'll be in familiar terrain.
9. Open QuickBooks, and the first thing you should do is register your QuickBooks using the validation code that was issued to you.
10. Go to the Help menu, then click on Manage License, and finally sync QuickBooks License Online.
11. Finally, sit back and relax while your QuickBooks gets updated to a multi-user license right in front of your eyes.
