[求助]ENGINE授权许可文件为何不起作用

<P>我用的ENGINE授权许可文件内容如下：</P>
<P>designer,91,ecp279970139,none,5H8LJALHPCE5Y7ZPM152<BR>arcgisengine,9,ecp123456789,none,MJJAC7EPTJJLTK118036<BR>3dengine,91,ecp387942929,none,NKMGJE0LX0S5RJE15061 <BR>gdbedit,91,ecp226004169,none,ZZYP340LLBC2LMZ59250 <BR>networkengine,91,ecp694040297,none,KGEAFAXSTLJSA1GJH027 <BR>spatialengine,91,ecp351946892,none,ZZ1THK6Z4HBPDPF44025 <BR>standardengine,91,ecp172022654,none,JFC42XKEJ1L5GTJ89099 </P>
<P>在VS.NET2005里说：需要designer　license,可授权文件里明明不是有吗？为什么呀？</P>
<P>大侠帮忙啊！！！</P>
