在安装的时候出现一个错误提示“安装程序无法复制文件CONVLOG.EX_”，上网找了很多资料，都说是因为版本问题，考虑到自己的服务器安装的是2003 SP1，后来打了补丁到SP2的，也就认为是版本问题，结果下了很多SP2版本也不行，再到网上搜索。有个说法是在运行－中输入“esentutl /p %windir%/security/database/secedit.sdb ” 就可以了，试了一下，还真管用，虽然不知道什么原理，但还是把它记录下来吧，以后用！

 

C:\Documents and Settings\Administrator>esentutl /p %windir%/security/database/s
ecedit.sdb
