When you Actiavte or open QuickBooks, you see one of these error messages:
Why this is happening:
Important: Once started, be sure to install any updates marked critical.
To install the latest updates in Windows:
Note: An update to your anti-virus program may have identified a Virus in QuickBooks. This is usually a false positive and the QuickBooks file is not truly infected.
Note: You may need to re-install your software. Have your license number and product number for your version of QuickBooks ready.
To find your license and product numbers:
Note: If you have previously registered your QuickBooks software, you can get help finding your license number or key code with our License Look Up Tool.
Note: If you have not previously registered your QuickBooks software our support article on missing or illegible installation numbers may help.
Try these steps in the order shown. If the first one fixes the problem, you do not need to try the other steps.
