Good to see you here, @larrry56. 

I would like to provide some information about the QuickBooks Desktop (QBDT) version compatible with Microsoft Windows 11.

As of the moment, only QBDT 2022 R3 or later is compatible with Windows 11 64-bit. For more details, feel free to check this article: QuickBooks Desktop Microsoft Windows 11 Compatibility.

Also, to verify what operating system is required to run QBDT 2021, check out the system requirements page. This is helpful to ensure you always get the best experience when using the program.

Additionally, here's a compilation of awesome help articles that you can access for further assistance in performing your QuickBooks tasks.
