请帮忙解决64位系统下不能加载32位的动态文件Cannot load 32 bit extw32.dll,该如何处理

请帮忙解决64位系统下不能加载32位的动态文件Cannot load 32 bit extw32.dll
原文如下
The   software   worked   on   2   computers,   one   running   Vista   and   one   running   XP.   It   failed   to   load   on   4   similar   computers.   Among   the   many   errors   I   get   is   "Cannot   load   32   bit   extw32.dll ".   On   some   computers,   plug   and   play   runs   properly,   without   running   setup.   On   others,   I   run   setup   and   the   dentalsoft   folder   goes   into   program   files   and   then   setup   stops,   not   installing   anything.  
这是在英文中使用得出的错误提示,其有四台电脑分别有Vista   与   Xp两种系统,但分别各有一台不能使用
请问高手应该如何解决
