If you have a Windows ARM64 computer (some of the latest MS Surface or such, usually "Snapdragon" CPU), download the version for Windows for ARM64.
If you have a reasonably recent computer (post-2018) with Intel or AMD processor (x86_64 architecture, something called "Core", "Ryzen", "N150", "Pentium", ...) running Windows 11 without restrictions, try the Qt6-based Windows 10+ version.
If you have a very old computer (2008-2018, those unable to upgrade to Windows 11), try the Qt5-based Windows 7+ version.
