Google浏览器的离线安装操作全攻略如下：
1. 首先，你需要下载Google浏览器的离线安装包。你可以从Google官方网站或其他可信的网站下载。确保下载的是最新版本的离线安装包，以便获得最新的功能和修复。
2. 下载完成后，将离线安装包解压到一个文件夹中。例如，你可以将其命名为“google_chrome_offline_installer”。
3. 打开你的计算机上的记事本或文本编辑器，然后按照以下步骤编写一个批处理文件（.bat文件）：

@echo off
setlocal enabledelayedexpansion
rem 设置变量
set "chrome_path=%cd%\chrome.exe"
set "chrome_version=78.0.3904.108"
set "chrome_url=https://dl.google.com/chrome/install/%chrome_version%/chrome-%chrome_version%-stable-x86_64-offline.exe"
rem 设置安装路径
set "install_path=C:\Program Files\Google\Chrome\Application\chrome.exe"
rem 设置安装参数
set "install_args=--unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value="" --unsafe-value
