A newer cross-platform UI; a good starting point for a first install.

Choosing between the two interfaces
Both are v2rayN clients, not separate subscription services. Desktop uses a cross-platform interface, while WPF retains the classic Windows UI. Buttons, menus and settings may be in different places, so a guide screenshot alone doesn't mean your installation is wrong. If you already have a setup, check which interface you're using before switching.
Both Windows downloads on this page are x64. In Windows, open Settings → System → About and check System type; the exact labels may vary. A processor's architecture does not guarantee that the installed OS or its compatibility layer meets the requirements. Check the release notes for other architectures rather than renaming a file to make it fit.
Extracting, installing and launching for the first time
Save the download to a local folder you can write to, and wait for the browser to show that it has finished. Extract the entire ZIP archive to a folder, then run the installer inside; don't launch it from the archive viewer's temporary preview. After the setup wizard finishes, launch the client from the system's app menu to avoid mistaking an older folder's copy for the installed version.
If startup fails, keep the original error message. Missing runtime components, write-permission failures and core startup errors have different causes and require different fixes. First install any runtime required by that edition, then check the logs. For your first connection, import a subscription, choose a node, set the system proxy and confirm the app can access the network. See the quick-start guide for full steps.
