无法在Android Studio上创建新的AVD

我刚刚安装了Android Studio版本0.8.6，我正在尝试创建一个新的AVD，但出现错误，错误是

此目标没有可用的CPU/ABI系统映像。它让我选择的唯一目标是Android 4.4W-API级别20

我可以看到SDK管理器中有9个安装包，包括：

Android Wear ARM EABI v7a系统图像，Android API 20，第1版

但当我同意T&C后尝试安装时，我会收到以下错误日志：

我被困在这里，不知道该怎么办。

您应该首先检查您是否已授予C:/>驱动器和相应目录的写入权限。

其次，您应该尝试以管理员身份运行Android Studio和SDK管理器。

谢谢，是的，您必须以管理员身份运行
