利洽科技-nsNiuniuSkinUI - NSIS 实现了electron 的安装包美化，免费，便捷。
下面我整理了一些关于它的微调，使其安装卸载更加简单快捷。

1. 默认展示安装路径部分

（1）将moreconfiginfo标签visible 设置为 true，切换[btnShowMore] [btnHideMore]下拉按钮 （SetupScripts>nim>skin>configpage.xml）

<?xml version="1.0" encoding="utf-8"?>
<Windows>
   <!-- 安装目录 -->
   <VerticalLayout>
   	<VerticalLayout width="480" height="250" roundcorner="5,5" bkimage="file='form\pic.png'">
	
	</VerticalLayout>
	<VerticalLayout bkcolor="#FFFFFFFF">
		
	<VerticalLayout name="moreconfiginfo" bkimage="form\bk_down.png" visible="true" height="130">
	  <Control height="25" />
	  <Label font="5" textcolor="#FF333333" text="安装路径：" padding="40,0,30,0" />
	  <HorizontalLayout height="32" padding="40,6,30,0">
      <RichEdit  name="editDir" text="" textcolor="0xFF000000" inset="5,8,2,2" bkimage="public\edit\edit0.png" autohscroll="false" bordervisible="true"  bordersize="1" bordercolor="0xFFD1D1D1" focusbordercolor="0xFFD1D1D1" wantreturn="false" wantctrlreturn="false" multiline="false" width="360" />
      <Control width="10" />
      <Button name="btnSelectDir" width="40" height="32" normalimage="form\btn_path_normal.png" hotimage="form\btn_path_hovered.png" pushedimage="form\btn_path_pressed.png"  />      
      </HorizontalLayout>
	  
	 <HorizontalLayout height="23" padding="40,5,80,0">
        <Label font="0" textcolor="#FF999999" width="150" text="所需空间：100M" />
		<Label font="0" name="local_space" width="150" textcolor="#FF999999"  />
		<Control />
     </HorizontalLayout>
	</VerticalLayout>
	<Control />
	<HorizontalLayout height="20" padding="95,25,0,0" >
      <CheckBox name="chkAgree" width="125" heigh="20" font="7" text="我已经阅读并认可" textcolor="#FF333333" selected="true" valign="center" align="left" textpadding="20,0,0,0" normalimage="file='public/CheckBox/check_no.png' dest='0,2,16,18'" normalhotimage="file='public/CheckBox/check_no.png' dest='0,2,16,18'" selectedimage="file='public/CheckBox/check_yes.png' dest='0,2,16,18'" selectedhotimage="file='public/CheckBox/check_yes.png' dest='0,2,16,18'"/>
      <Button name="btnAgreement" width="180" font="7" text="《软件许可及服务协议》" textpadding="0,0,0,0" textcolor="0xff00bb96" align="left" />
	  <Control />
    </HorizontalLayout>
	<Button name="btnInstall" padding="95,10,0,30" width="290" height="40" normalimage="form\btn_installation_normal.png" hotimage="form\btn_installation_hovered.png" pushedimage="form\btn_installation_pressed.png" disabledimage="form\btn_installation_disable.png" font="6" textcolor="0xffffffff" disabledtextcolor="0xffffffff" margin="0,10,0,0" text="一键安装" />
	
	</VerticalLayout>
	<Button float="true" visible="false" inset="0,5,5,0" pos="220,230,260,270"  name="btnShowMore" width="40" height="40" normalimage="form\btn_down_normal.png" hotimage="form\btn_down_hovered.png" pushedimage="form\btn_down_pressed.png" />
	<Button float="true" visible="true" inset="0,5,5,0" pos="220,230,260,270"  name="btnHideMore" width="40" height="40" normalimage="form\btn_up_normal.png" hotimage="form\btn_up_hovered.png" pushedimage="form\btn_up_pressed.png" />
	<Include source="licensepage.xml" />
   
   </VerticalLayout>
</Windows>

（2）设置初次加载尺寸为480 * 500（路径： SetupScripts>nim>ui_nim_setup.nsh>DUIPage函数 #添加设置初始高度 500 ）

Function DUIPage
    StrCpy $InstallState "0"	#设置未安装完成状态
	InitPluginsDir   	
	SetOutPath "$PLUGINSDIR"
	File "${INSTALL_LICENCE_FILENAME}"
    File "${INSTALL_RES_PATH}"
	File /oname=logo.ico "${INSTALL_ICO}" 		#此处的目标文件一定是logo.ico，否则控件将找不到文件 
	nsNiuniuSkin::InitSkinPage "$PLUGINSDIR\" "${INSTALL_LICENCE_FILENAME}" #指定插件路径及协议文件名称
    Pop $hInstallDlg
   	
	#生成安装路径，包含识别旧的安装路径  
    Call GenerateSetupAddress
	
	#设置控件显示安装路径 
    nsNiuniuSkin::SetControlAttribute $hInstallDlg "editDir" "text" "$INSTDIR"
	Call OnRichEditTextChange

	#设置安装包的标题及任务栏显示  
	nsNiuniuSkin::SetWindowTile $hInstallDlg "${PRODUCT_NAME}安装程序"
	nsNiuniuSkin::ShowPageItem $hInstallDlg "wizardTab" ${INSTALL_PAGE_CONFIG}
	
	nsNiuniuSkin::SetControlAttribute $hInstallDlg "licensename" "text" "服务条款"
	#nsNiuniuSkin::SetControlAttribute $hInstallDlg "btnAgreement" "text" "  用户许可协议"

    #设置初始高度 500
	nsNiuniuSkin::SetWindowSize $hInstallDlg 480 500
		
    Call BindUIControls	
    nsNiuniuSkin::ShowPage 0
FunctionEnd

2. 双击安装包和卸载时 默认杀掉当前运行进程，无需提示用户手动关闭应用程序

（代码最下方添加如下钩子函数 路径： SetupScripts>nim>ui_nim_setup.nsh）

#进入安装程序时回调
Function .onInit
    #硬编码杀掉指定进程
    nsProcess::_KillProcess "React18-Electron-Temp.exe"
    #或者
    nsProcess::_KillProcess "${EXE_NAME}"
FunctionEnd

#当卸载程序接近完成初始化时调用
Function un.onInit
	#硬编码杀掉指定进程
    nsProcess::_KillProcess "React18-Electron-Temp.exe"
    #或者
    nsProcess::_KillProcess "${EXE_NAME}"
FunctionEnd

3. 自定义许可协议（改这两个文件）

SetupScripts>nim>ui_nim_setup.nsh>licence.txt
SetupScripts>nim>ui_nim_setup.nsh>licence.rtf
最终默认使用licence.rtf 想办法生成 rtf 文件

4. 包体压缩

SetupScripts>nim>nim_setup.nsi
根据需要配置压缩即可

#包体压缩
#SetCompressor lzma ZLIB ZLIB(固实)  BZIP2 BZIP2(固实) LZMA LZMA(固实) 极限压缩

; 设置压缩选项 lzma 压缩率高 解压安装快  打包慢
SetCompress auto
SetCompressor /SOLID lzma
SetCompressorDictSize 32

5. 快捷方式添加UCA盾牌

（1）SetupScripts>nim>nim_setup.nsi

#==================== NSIS属性 ================================
#针对Vista和win7 的UAC进行权限请求.
#RequestExecutionLevel none|user|highest|admin
RequestExecutionLevel admin

（2）electron项目 package.json 中添加

   "win": {
      "requestedExecutionLevel": "requireAdministrator"
    },

  "build": {
    "asar": true,
    "icon": "./public/ico/favicon.ico",
    "productName": "React18-Electron-Temp",
    "appId": "React18ElectronTemp",
    "win": {
      "requestedExecutionLevel": "requireAdministrator"
    },

      "uninstallerIcon": "./public/ico/favicon.ico",
      "createDesktopShortcut": true,
      "createStartMenuShortcut": true,
      "shortcutName": "React18-Electron-Temp",
      "artifactName": "${productName}-setup-${version}_${os}_${arch}.${ext}"
    },
    "directories": {
      "output": "build"
    },
    "files": [
      "!node_modules/*/{CHANGELOG.md,README.md,README,readme.md,readme}",
      "!node_modules/*/{test,__tests__,tests,powered-test,example,examples}",
      "!node_modules/*.d.ts",
      "!**/*.map",
      "!**/electron-log*",
      "!node_modules/rc-*/**/*",
      "!node_modules/xlsx/**/*",

      "!local-debug/**/*",
      "dist/**/*",

    ],
    "extraResources": [
      {
        "from": "./local-debug",
        "to": "."
      }
    ]
  },
