How to build and install SoftEther VPN on Windows ARM64

This document describes how to build SoftEther VPN for Windows ARM64 and how to install the VPN Client and Neo6 virtual network adapter on Windows on ARM devices.

Requirements

• Build host: Windows x64

• Target device: Windows 10 / Windows 11 ARM64

Building

**Notes before building**: ARM64 builds are cross-compiled from an x64 Windows host. An existing x64-native build is required to generate hamcore.se2.

1. Follow BUILD_WINDOWS.md

2. Build x64 (Native): From the build menu, select x64-on-x64. Complete the build successfully. This build is required to generate shared resources

3. Build ARM64 (Cross-Compiled): From the same build menu, select arm64-on-x64. Build the ARM64 version of SoftEther VPN.

4. Building the Neo6 Virtual Network Adapter (ARM64)

   Open the following project in Visual Studio:

   .\src\Neo6\Neo6.vcxproj 
   

   SoftEther VPN Client uses the Neo6 virtual network adapter.

   Driver Output Files The ARM64 driver package includes:

   Neo6_arm64_VPN.sys
   Neo6_arm64_VPN.inf
   

   Driver Signing and Installation (Windows ARM64)

   Enable test-signing mode: bcdedit /set testsigning on
   Reboot the system.
   Testing signing:
   Install the Neo6 ARM64 driver.
   

Summary

SoftEther VPN can be cross-compiled for Windows ARM64 on an x64 host VPN Client works natively on Windows on ARM Neo6 ARM64 driver requires Microsoft signing for production use Test-signing is suitable for local development only
