安装SQL2005时，在选择是否有密码时，点击下一步后，出现提示框，内容如下：
setup is not able to connect to the database of microsoft SQL Server 2000(WinCC)

you could reset your sa user password with your Enterprise Manager application (you will find more information in read first document).

or you could remove microsoft SQL Server 2000(WinCC) from your computer and run this setup again!

press retry to-enter your password or press cancel to exit out of setup。

如果点击“重试”，还是这样，点击“取消”则退出安装。
请问如何解决？？
