Let me share some information about the QuickBooks Desktop system requirement, @pdpj126.
QuickBooks Desktop 2019 only requires Windows 10, all editions including 64-bit. If you have a higher OS version it would be better. Just make sure to use Windows natively and not through an emulator or virtual environment.
