在用非管理员用户安装Android Studio遇到下面这个问题：

Config path ‘C:\Users\Administrator\.AndroidStudioPreview\config’ is invalid.
If you have modified the ‘idea.config.path’ property please make sure it is correct,
otherwise please re-install the IDE.

之所以会出现这个问题是根本原因是我使用的不是管理员用户，其实只要用管理员用户操作，这个问题将不存在。下面提供的解决方案基于非管理员用户。

Google得到Stack Overflow上大神的回答，打开 android-studio安装目录下的bin\idea.properties，比如 C:\Program Files (x86)\Android\android-studio\bin\idea.properties.

你将看到：

#---------------------------------------------------------------------
# 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}/.AndroidStudioPreview/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}/.AndroidStudioPreview/system
....etc

将idea.config.path#去掉保存。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=${user.home}/.AndroidStudioPreview/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}/.AndroidStudioPreview/system
....etc

这个方法解决了一些人的问题。但我的问题依然存在，索性将配置改成如下问题即可成功解决：

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.config.path=D:/AndroidStudio/.AndroidStudioPreview/config

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.system.path=D:/AndroidStudio/.AndroidStudioPreview/system
