Intuit recommends several solutions for this problem. The first solution may solve your problem, or you may need to try them all to resolve the issue. For best results, perform the solutions in order shown.
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 the license number and product code don't match, then uninstall and reinstall with the correct license number and product code.
The QuickBooks Component Repair Tool is designed to automatically diagnose and fix issues with Microsoft .NET Framework, C++, and MSXML.
It is sometimes necessary to uninstall QuickBooks, rename installation files left behind, and then reinstall QuickBooks, otherwise known as a clean install. This may be required when a QuickBooks function is damaged or when simply reinstalling QuickBooks does not correct an issue. Follow the steps in the reinstall using a clean install article.
Sometimes it is necessary to try a new Windows user to rule out user damage.
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.
