      • "Desktop development with C++"
      • MSVC v142 or v143 toolset (matching UE4 branch requirements)
      • Windows 10 SDK (10.0.xxxxx)
      • C++ CMake tools (optional for some workflows)
    • Ensure the x64 native compilers and x64/x86 cross tools installed.

  4. Windows SDK & Tools

    • 7-Zip or similar for archive handling.

  6. GPU Drivers

    • Latest drivers supporting DirectX 11/12; for development with ray tracing or DX12 features, ensure drivers are up to date.

Step-by-Step: What to Do

7. Build Configuration for x64

  1. Visual Studio Configuration (Windows)
    • Open UE4.sln.
    • Select configuration: Development Editor or DebugGame Editor as needed.
    • Select platform: Win64 (ensure x64 selected; add if missing via Configuration Manager).
    • Build Solution (or target specific projects like UE4Editor).
  2. Command-line Build (Windows)
    • Use Build.bat or RunUAT.bat for packaging; specify -platform=Win64 where required.
    • Example: Engine/Build/BatchFiles/Build.bat UE4Editor Win64 Development -WaitMutex -FromMsBuild
  3. Linux Build
    • Use make or Engine/Build/BatchFiles/RunUAT.sh and build scripts specifying Linux x86_64 targets.
    • Example: ./Engine/Build/BatchFiles/RunUAT.sh BuildEditor -platform=Linux -target=UE4Editor -configuration=Development
