I'm including below a link to the System Requirements for PB 2022 and you'll note (happily, I hope) that Windows 11 is officially supported:

Invariably with every new version, people raise several questions in the Q&A due to their unfamiliarity with the changes that have been made to the product. I encourage everyone to invest a couple of minutes to review what's new in PB 2022, even if you tested the beta release. Below are links to this information for PowerBuilder and PowerServer:

Yes, the current test can run on win7, but according to the official statement, it is at your own risk. thanks
