Hello there, @sirons.
Let me give you some troubleshooting steps that will help you get back to your business.
If your QuickBooks Desktop pro is still installed in your Windows 7 computer, I suggest creating a portable company file in your QuickBooks Desktop then save it on a thumb drive. This will help you restore your company file to your Windows 10 computer without having issues.
Please make sure that when creating a portable file, you’ll select the most updated file to avoid missing data on your company file.
To create a portable file, here’s how.
Once done, you can now transfer your thumb drive to your Windows 10 computer and restore your company file as a portable file in QuickBooks Desktop.
If the issue persists, I advise contacting our Phone Support Team. They have the proper tools to pull up and check what causes the issue.
To reach them, here's how.
For QuickBooks Pro, Premier, plus, their schedule is 6:00 AM-6:00 PM PT Monday-Friday and 6:00 AM-3:00 PM PT on Saturdays.
I’ll be leaving you this help article if you have any other issues.
Please let me know if you have other questions. Have a nice day!
