System requirements for QuickBooks Desktop 2021

If you're using Windows 8.1, Microsoft will no longer provide security updates or support for PCs running Windows 8.1 after Jan 10, 2023. For your data’s security, we recommend upgrading your operating system to a supported version before installing QuickBooks.

Are you using Windows Server 2012?

Microsoft will no longer provide security updates or support for PCs running Windows Standard and Essentials Server 2012 and Server 2012 R2 after Oct 10, 2023. For this reason, QuickBooks 2022 won't support Windows Server 2012 and can’t be installed on it.
