[NSH]Electron Builder中安装第三方软件

Electron Builder支持NSIS格式输出构建产物。NSIS可以使用NSH来定制安装过程，以下为安装VC Redist示例：

!macro customHeader 
  ;vc redist需要管理员权限
  RequestExecutionLevel admin
!macroend

!macro customInstall
  ; install vc-redist if not installed
  ReadRegStr $1 HKLM "SOFTWARE\WOW6432Node\Microsoft\VisualStudio\14.0\VC\Runtimes\x64" "Installed"
  StrCmp $1 1 installed

  ;not installed, so run the installer
  ;这是在安装的过程中执行，所以需要打包的时候把安装包提前集成进来，或者从网络下载
  ExecWait '"$INSTDIR\resources\VcRedist\2022\14.38.33135.0\x64\VC_redist.x64.exe" /install /quiet /norestart'

  installed:
  ;we are done
!macroend

对应的electron-builder.json配置项

{
  "nsis": {
    "include": "vc-redist/install-vcredist.nsh"
  }
}
