我找到原因是因为这个：

Cause.

The cause of the error was that the student was applying an Chiversion of SP1 for SQL Server 2008 on an instance installed in English language. The "Select Features" page has a description message on the top right side of the page explaining what is occurring but the student did not read it:

"The language of SQL Server instance MSSQLSERVER does not match the language expected by the SQL Server update. The installed SQL Server product is English (United States) and the expected SQL Server language is Chinise(China)."

翻译大概的意思就是语言不同，安装的产品是英文版，跟预期的数据库中文版不相符，所以出现这种错误，去哪里设置成统一的英文呢？
