Thanks for sharing your situation, Kathy.

As for the details shared by my colleague Angelyn_T on this thread, the Install Later option under the QuickBooks Update Service window will not be available when a force QuickBooks update is needed. If you have the Install Now button, you'll want to click that to establish an update and open your QuickBooks program.

Otherwise, download the QuickBooks Tool Hub. This is helps to diagnose and resolve common issues when you're unable to open a company file. 

Here's how:

1. Close QuickBooks.
2. Download the most recent version (1.5.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab.  The version will be on the bottom.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
6. Once the  QuickBooks Tool Hub is open, select Program Problems.
7. Select Quick Fix my Program.
8. Start QuickBooks Desktop and open your data file.
