SQLServer 2012 无法安装部分功能

Question

由于以前安装过，后来由于空间太小，就卸载进行重新安装（这段时间内OS安装过很多补丁），无法安装部分功能，特别是引擎失败。主机OS是windows8

Answer 1

Sounds didn't clean up previous sql installation properly, delete all related registry keys then try again.

Answer 2

Hi，

就像@rmiao说的那样，应该是之前的数据库没有卸载干净导致的，你可以参照着篇文章把sql server 卸载干净：http://msdn.microsoft.com/zh-cn/library/hh231731(v=SQL.110).aspx ；还有那些注册表啊，残留文件之类的啊都一律清除。实在不行，你可以在网上下载一个工具帮助你完全卸载sql server2012.

Thanks,
Amy Peng
