Desktop version: Uses a modern cross-platform interface with a structure, settings navigation, and overall experience more consistent with other desktop systems. It suits first-time v2rayN users and those who prefer the current desktop direction.
Classic WPF version: Retains the traditional Windows client layout. Navigation for server lists, subscription groups, system proxy, and routing settings follows familiar older workflows, making it suitable for users accustomed to the classic interface.
Both options target 64-bit Windows. If the device runs current Windows desktop apps normally, start with the Desktop version. If existing tutorials, configuration steps, or habits rely on the WPF interface, the classic WPF version makes menu locations easier to follow.
