Only 64-bit Windows is supported. Download latest Husarnet Windows installer and run the executable.
After installer finishes working, service will start and you should be able to use Husarnet through the command line.
Husarnet CLI uses emojis in some outputs. These are not supported by standard cmd.exe and powershell.exe on Windows - if you see random characters here and there, change your terminal emulator to the one that supports full Unicode. Good one is official Microsoft's Windows Terminal
If you opened a terminal window before installing Husarnet, you might need to refresh your PATH (simply start new terminal session).
Some commands need Administrator-level privileges. If you see errors, try running elevated command prompt (Right-click and Run as administrator...)
