前几天同事机子由于中毒太深，重新安装了操作系统，在重装SQL SERVER2000，结果在安装到数据库访问组件（MDAC）时出现了错误提示：
SQL Redist content: Command line option syntax error. Type Command /? for Help.
我试着取消安装，从应用程序删除已经安装部分，并删除了安装文件夹，多次重新安装，问题依旧存在，没办法上网搜索，最终微软站点找到答案。
This problem may occur if all the following conditions are true:
• You run the SQL Server 2000 SP3 Setup.bat file from a folder that contains double-byte character set (DBCS) characters in the folder name.
• An ODBC client program that uses the Sqlsrv32.dll file is running on your computer.
同事机子的SQL SERVER2000安装盘的所在文件夹起了个中文名字，而汉字正是所谓的双字节。将文件夹名字改回英文再装，问题解决了。
