1、在安装向导过程中，出现如下错误：
{英文原意如下
When you install Microsoft SQL Server 2005, you receive the following error message:
There was an unexpected failure during the setup wizard. You may review the setup logs and/or click the help button for more information.}
2、当我检查C:/Program Files/Microsoft SQL Server/90/Setup Bootstrap/LOG/
Microsoft SQL Server 2005 9.00.1399.06

3、当我检查到日志文件SQLSetup0001_CSZ_Core.log，发现在日志文件末尾有如下的错误提示：
{英文原意如下：
When you examine the SQLSetupNumber_ServerName_Core(local).log file at this point, you notice the following error message at the end of the log file: }

4、问题解决
在d:盘根目录下建立sqlserver2005Setup目录，再在d:/sqlserver2005Setup/下创建2个目录
/Servers
/Tools
如 果是2个cd的安装程序，将cd1上的所有文件拷贝到Servers目录下，将cd2目录下的所有文件拷贝到Tools下；如果是一个dvd的安装程序， 则分别把dvd上的Servers和Tools目录下的所有文件分别拷贝到d:/sqlserver2005Setup/Servers和d: /sqlserver2005Setup/Tools
再进行安装应该就没有问题。
还有需要注意的问题
安装到上述错误的时候，SQL Server2005很多文件已经安装到硬盘上了，所有你重新安装的时候，可能会遇到
1、提示磁盘空间不够
目标磁盘中的空间不足，无法执行当前的 SQL Server 安装。若要继续，请释放磁盘空间以安装所选功能、为此次安装选择较少的功能或将所选功能安装到另一个驱动器中。
2、安装仍然失败
所以建议你重新安装之前，到添加删除程序里把SQL Server2005卸载掉！
上述问题是8月份我在一个客户那里搞了一个晚上都没有搞定，最后第二天早上在宾馆里上网到微软的网站上找到了答案，真是让人哭笑不得。
微软网站上标题为：

------------------------------------------------------------------------
性能计数器问题，主要是卸载SQL2005，再重新安装的错误，这方面的文章在网上很多，网友可搜索一下。
关于找不到网上这样的疑问同样很多，但是没有明确的解答。这里说说我是怎么解决的。
应该说这是MSDN SQL2005安装程序的一个bug（不是十分确定），在SQL2005安装目录有两个子目录，一个是Servers目录， 一个是Tools目录，当初我只把Servers拷贝我硬盘上了，所以安装时如果选择了工作站组件、联机丛书和开发工具选项，安装到最后，就会提示你 找不到（或其它安装不成功的提示信息），其实安装sql时先不要选该项，这样就可以安装成功，最后安装Tools的setup程序，它就是 仅安装该选项的安装包。
-------------------------------------------------------------
假如，以上这种办法还是出现找不到类似的错误，那么你可以在上面那个办法的基础上，打开TOOLS文件夹（有的可能是CD2文件夹），找到TOOLS/Setup/SqlRun_Tools.msi并，运行，然后按照正常的安装流程来，这样应该可以解决了
题外话：我熬了好几个夜，把SQL2005装了删，删了装，终于装上了，真是辛苦啊~~。以上是我的安装解决办法的总结，有的是网站感觉比较有用的转载，有的是自己实际经历的过程的记录~~！
