Windows Setup by Paravis — C++ port

Native Win32 port of Windows_installer_NEW\setup.au3.

Build

Requirements: Visual Studio 2022 (Desktop C++) and CMake 3.20+.

build.cmd

Outputs:

build_x64\Release\setup_x64.exe
build_x86\Release\setup_x86.exe

The executables use a static CRT, are GUI subsystem, and use the same asInvoker manifest / Common Controls 6 as the AutoIt builds.

Preview

• setup_x64.exe /preview or an executable named setup_preview*.exe starts preview mode: fixed 307×259 position, all buttons enabled, no src_*.exe helper, preview wallpaper.
• The ported setup_preview.exe in ..\Windows_installer_NEW is the x64 build used this way.

Deployment

On a PARAVIS flash the two Windows Setup WIMs are:

• \efi\Paravis\Boot\ws64.wim, image 1, \Windows\Setup.exe — x64 build
• \efi\Paravis\Boot\ws86.wim, image 1, \Windows\Setup.exe — x86 build

Winpeshl.ini in both WIMs already launches %SYSTEMROOT%\setup.exe. The launcher starts the real setup from X:\sources\setup.exe.

The window is layered with color key 0xABCDEF. The Montserrat fonts are embedded as RCDATA; the 1024×768 wallpaper is embedded as a lossless PNG and decoded with GDI+ at startup. This keeps each executable around 1 MB. The UI is the same 376/410/360-wide layout as the AutoIt version, with native buttons. GDI+ and ole32 are standard components of the Windows Setup boot.wim (verified in the target image).

Behaviour

• Searches all drives for \WindowsESD\NOT.DEL or \efi\Paravis\Windows\NOT.DEL.
• Warns and exits if both image folders are present.
• Finds \efi\Paravis\Boot\NOT.DEL for src_x64.exe / src_x86.exe and Total Commander.
• Uses %WINDIR%\SYSWOW64 to select the x64 UI; firmware_type selects Legacy vs UEFI for the x86 UI.
• Builds the same X:\sources\setup.exe /installfrom:... /m:... [/unattend:...] command lines as AutoIt.
• Disables Windows buttons when the corresponding ESD image is missing.
• Reboot button exits the launcher (the WinPE startup script performs the reboot).
• Debug log: set PARAVIS_DEBUG_LOG=1 to write %TEMP%\winsetup_cpp_debug.log.
