到官网下载windows环境下的github，在安装时出现以下问题
An error occurred trying to download 'http://github-windows.s3.amazonaws.com/GitHub.application'. See the setup log file located at 'C:\Users\。。。\AppData\Local\Temp\VSD7580.tmp\install.log' for more information.
由此可知网址‘http://github-windows.s3.amazonaws.com/GitHub.application‘无法被访问，下载文件
可以将该网站修改为‘https://github-windows.s3.amazonaws.com/GitHub.application‘ 直接在ie等浏览器中访问，就可以直接下载安装。。。证明可以。
