关于sql server 2005的安装问题
谢谢好心帮我解答问题的人！！！！

我在windows   2003   SP1的系统上安装了sql   server   2005,   但是由于在位sql   server2005打sp1的补丁时出错，   所以我卸载了sql   server2005。
并且删除了各个sql   server有关的安装文件和数据文件，   并且在注册表中也删除了sql   server的key。
  然后重新启动server,之后重新安装sql   server   2005时，总是在安装Microsoft   SQL   Server   2005   Setup   Support   Files时，出现错误，详细的错误信息如下：
Error   occured   during   the   installation:
Error   1603   installing   Microsoft   Sql   server   2005   setup   files,
See   log   file   for   more   information,
Fatal   error   during   information.

下面是log   file   的一部分：

MSI   (s)   (A0:48)   [18:16:10:901]:   MainEngineThread   is   returning   1603
