谷歌浏览器Chrome升级出现如下错误的另类解决方法：
谷歌浏览器Chrome升级出现如下错误： 
无法获得更新服务器（错误：7） 
Update server not available (error 7) 
Google Update Installation failed with error 7 

在之前一篇文章：谷歌浏览器Chrome升级失败的解决方法中介绍了通过设置系统的环境变量TMP为默认值来解决升级Chrome时出现“错误：7”的办法。不过在最近谷歌发布的chrome_installer.exe安装包已经能够解决TMP被修改到其它位置的情况。

然后在最近升级到3.0.193.1版本的Chrome时“无法获得更新服务器（错误：7） ”的错误再次出现，尝试修改TMP变量为默认值仍旧无法升级成功。

经过一番折腾（主要是利用chrome_installer.exe –verbose-log生成的安装日志）经过成功升级。

解决办法：

将Chrome安装目录（C:\Documents and Settings\Administrator\Local Settings\Application Data\Google\Chrome\Application）中保留的旧版本的目录删除，如:3.0.195.1,3.0.193.1，只保留最新Chrome的版本的目录和“chrome.exe”、“First Run”文件，然后启动Chrome再次启动自动更新，或者使用下载版的chrome_installer.exe直接安装。
