Hi there suegibbs-inreach,
Thanks for reaching out about your QuickBooks Desktop program. It's a great tool able to help you keep track of sales and expenses of your company so you know the profitability of your company. I can point you in the right direction for assistance with opening your QuickBooks Desktop file.
If you get an error when trying to open your QuickBooks Desktop software, I recommend reaching out to the QuickBooks Desktop support team outside of the Community. They'll be able to verify your software is correctly registered in the system to be able to open the program. You can reach them using the methods outlined in the QuickBooks Dekstop support policies.
If you have any other questions, feel free to reach out here.
