VC的Bug：Visual Studio 6.0 中出现错误消息“Setup Was Unable to Create a DCOM User Account”（安装程序无法创建 DCOM 用户帐户）
花了两天时间装vc6.0，微软官方已经没有了，找了个自称是官方原版镜像的下载后，总在安装最后一步出现Setup Was Unable to Create a DCOM User Account……，本人xp系统，上网查如下——>
在安装vc时，最后总出现：setup was unable to create a DCOM user account in order to register microsoft visual studio\common\tools\vs_ent98\valec.exe 然后就提示安装不成功！
这是Visual Studio的一个BUG，只出现在Windows 2000/XP下。如果你不使用Visual Studio Analyzer，可以在安装时选择Custom，然后在Enterprise Tools中清除掉Visual Studio Analyzer。再安装就没有这个问题了。

When you run the Visual Studio 6.0 Setup program, you may receive the following error message:
Setup was unable to create a DCOM user account in order to register <path>\valec.exe
This first error message may be followed by a second message that indicates that Setup failed.
CAUSE
Visual Studio Analyzer, which is one of the products that is included in Visual Studio Enterprise Edition version 6.0, cannot create the local user account that it needs to run because of changes to the security policies for users in Windows 2000.

1. Use the Custom setup, on the Visual Studio 6.0 Enterprise - Custom page, click Enterprise Tools, and then click Change Option.
