在网上查了好长时间也没有办法解决.后面查到一个国外的网站: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=428315&SiteID=1,在这上面提到了解决办法:(This is a common problem with Win 2000 with some MS programs (e.g. MSOffice).
To solve this problem just rename or delete the "APPHELP.DLL" file in "SYSTEM32" directory.
)也就是说把SYSTEM32目录下面的APPHELP.DLL改名或者删除即可.
