推荐答案

我在 Windows 7 中遇到了类似的问题，并且在第一次从我的开始程序菜单运行 android-studio 快捷方式时遇到了以下问题.

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

问题是由于 Windows C: 驱动器中的写入权限造成的，并且显示了 Access is Denied 消息.以管理员身份运行程序会下载所有必要的组件，现在我可以启动 Android Studio IDE.

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:

Android Studio 最新版本(在 Windows 10 中的 1.3.2 中检查)中似乎不存在这些权限问题，并且无需以管理员身份运行"命令即可工作.如果旧/最新版本仍然存在问题，则可能是防火墙和代理问题.在这种情况下，请查看其他答案.

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.
