推荐答案
而从我做起程序菜单运行Android工作室的快捷方式，第一次，我一直面临着类似的问题在Windows 7中，得到了下面的问题。
I had been facing the similar problem in Windows 7 and got the below problems while running the android-studio shortcut from my start programs menu for the first time.
解决方案：以管理员身份运行
Solution : Run As Administrator
该问题是由于下在Windows中的写权限：显示驱动器和访问被拒绝信息。运行程序作为管理员下载所有必需的组件，现在我就可以开始Android的Studio IDE中。
The problem was due to the write permission in Windows C: drive and the Access is Denied message is displayed. Running the program as administrator downloads all the necessary components and now I can start Android Studio IDE.
更新：
这些权限问题似乎并不在工作室的Android最新版本（在Windows 10中1.3.2检查）存在和不工作以管理员身份运行命令。如果您仍然有与旧/最新版本的问题，那么它可能是你的防火墙和代理问题。在这种情况下，检查了其他的答案。
These permission issues doesn't seem to exist in Android Studio latest versions(checked in 1.3.2 in Windows 10) and works without the "Run as administrator" commands. If you still have the problem with the old/latest versions then it might be your firewall and proxy issues. In that case check out the other answers.
