标题: SQL Server 安装程序失败。
------------------------------
SQL Server 安装程序遇到以下错误:
SQL Server 2008 setup100.exe and setuppatch.exe cannot be run in this mode. If you are running setup100.exe, start setup.exe instead. If you are running setuppatch.exe, run it from the command prompt, as the user interface is not supported for this action. For more information about Setup, see SQL Server Books Online.
错误代码 0x84B20001。
怎么办
------解决思路----------------------
1、控制面板上所有SQL相关的卸掉。
2、如果vs可以卸也卸掉，不行的话卸掉里面自带的express
3、重装sqlserver
4、再重装vs
