安装好Android Studio后，启动时弹出如下信息：
Config path ‘C:\Users\Administrator\.AndroidStudio1.5\config’ is invalid.
If you have modified the ‘idea.config.path’ property please make sure it is correct,
otherwise please re-install the IDE.
2.原因分析:
程序无权限访问这个目录或者这个目录不存在！
3.解决方法：
打开 android-studio安装目录下的bin\idea.properties，有类似如下的内容
#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE config folder. Make sure you‘re using forward slashes
#---------------------------------------------------------------------
#idea.config.path=${user.home}/.AndroidStudio1.5/config
#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you‘re using forward slashes
#---------------------------------------------------------------------
#idea.system.path=${user.home}/.AndroidStudio1.5/system
....etc
在C盘新建一个目录android_studio_data， 然后把${user.home} 换成C:\android_studio_data， 然后所在行的idea前的#去掉(如果没有以上内容，直接添加以下内容，路径可自行设置) 。
添加或修改如下：
#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE config folder. Make sure you‘re using forward slashes.
#---------------------------------------------------------------------
idea.config.path=C:/android_studio_data/.AndroidStudio1.5/config
#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you‘re using forward slashes.
#---------------------------------------------------------------------
idea.system.path=C:/android_studio_data/.AndroidStudio1.5w/system
