I've got you covered in upgrading your QuickBooks Desktop, LeMild.

We appreciate you for performing some troubleshooting steps to upgrade your software. But first, let's make sure we update QuickBooks Desktop to the latest release. Once done, use the Rebuild Data tool to automatically fix minor company file data issues. Here's how:

1. Go to the File menu, then hover over Utilities and select Rebuild Data.
2. On the QuickBooks Information window, press OK. Follow the onscreen steps to save a backup.
3. Let the tool repair your file. It may take some time. QuickBooks may seem stuck, but as long as you can move your mouse, the tool is working.
4. When the tool finishes, press OK.
5. Go to the File menu. Then hover over Utilities and click Verify Data.
6. Let the tool check your file for data issues.

If QuickBooks doesn't find any problems, press OK. You can keep using your company file if you don't have any data damage. Then, select Rebuild Now if QuickBooks finds an issue with your company file.

If you’re still having data issues after rebuilding your company file, try again. If you still have data issues, use the QuickBooks File Doctor to fix your company file. You can check out this article for more details about fixing data damage on your QuickBooks Desktop company file: Fix data damage on your QuickBooks Desktop company file.
