vs2012安装 error occurred

 安装完vs2012之后，能打开文件，能读取C++文件，但是关闭程序的时候出现如下错误信息：     An error occurred while creating or opening the C++ browsing database file Intellisense and browsing information will not be available for C++ projects.     Ensure that Microsoft SQL Server Compact 4.0 is installed and that no other applications are accessing the file. If the problem persists, delete the file and reopen the solution.     解决办法：     1）重新安装vs；再不行的话用2）的方法；     2）在微软网站下载中心，下载相应的64位系统或者32位系统的 Microsoft SQL Server Compact 4.0,安装即可。
