法一：删除注册表中的HKY_LOCAL_MACHINE\SYSTEM|ControlSet001\Services\VSS，卸载重装。
法二：点击 setup目录下的 wpie15.exe .. 然后再次点击 setp.exe 安装 (后来是不用ACMBOOT.EXE安装， 用SETUP )
法三： 找到安装盘下的KEY.DAT文件，用记事本打开，内容如下：
REGEDIT4
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio6.0SetupVisual Studio 98SetupWizard]
"aspo"=dword:00000000
REGEDIT4在Win2000、WinXp下是没法导入注册表的，将其攺为：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio6.0SetupVisual Studio 98SetupWizard]
"aspo"=dword:00000000
另存为 reg.reg，双击导入注册表，再次安装。
安装成功后，若出现编译总出错，可能是路径不对，可按以下方法修改路径
如果你是按照初始路径安装vc6.0的，路径应为：
