QuickBooks V2016 works just fine on Windows 10 Pro 64-bit - I have it working. V2015 works as well because I converted to Windows 10 before V2016 was out. Earlier than V2015 is out of support and may not work.

I think the QB version is pre-2015 hence the problem John

So upgrade QuickBooks and keep Windows 10 - that would be my suggestion. Otherwise, format, reinstall Windows 7 and be ready for nearly 400 updates post SP1 (two days of updating).
Only way now is a clean install - unless the machine has a factory restore option(like Dell/HP models)
