When you register or open QuickBooks, you see one of these error messages:
Important: This issue can occur if your product is hosted by Right Networks and you access QuickBooks with WebConnect and then select to open the file without saving. If you use QuickBooks Enterprise and your product is hosted by Right Networks, you must save the file and then import it.
You may need to re-install your software. Have your license number and product number for your version of QuickBooks ready.
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.
To find your license and product numbers:
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.
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.
If these solutions don't resolve the issue, you can read discussions and post messages and questions relating to your issue on the Intuit QuickBooks Community site for free. You can contact an agent for additional guidance. Fees may apply.
