Hi TerriSum,

There's a big chance that you will be prompted to upgrade your operating system since QuickBooks 2020 needs at least Windows 8.1 or Windows 10. Check out the system requirements  for more details.

I recommend upgrading your operating system so you can use QuickBooks. I would understand if you'll experiment with some solutions to continue working on Windows 7. However, these may result in frequent errors or data damage. Having said that, I also suggest doing frequent backups whenever possible until you decide to upgrade your OS.

Let me know if you have more questions in mind. Take care and have a good one!
