Hi there mary53,
Thanks for reaching out about opening your QuickBooks Desktop. It's a great program able to help you keep track of sales and expenses so you can see the profit of your company. I can point you in the right direction for assistance with errors while starting up QuickBooks Desktop.
For assistance with errors seen when trying to connect to your QuickBooks Desktop, I recommend reaching out to the QuickBooks Desktop support team outside of the Community. They'll be able to view the error with you in a secure setting in order to help you get it resolved so you can get back to managing your books. You can reach them using the methods outlined in the QuickBooks Desktop software support policies.
If you have any other questions, feel free to reach out here.
