FCIAddFile(failed: code 1 [Failure opening file to be stored in cabinet],该怎么解决

FCIAddFile(failed: code 1 [Failure opening file to be stored in cabinet]
ActiveX发布最后一步，创建CAB文件，在命令行中输入"cabarc -s 6144 n demo.cab atl90.dll Polygon.dll demo.inf"后，
系统报错：

何解？求解答。

附上.inf文件
[version]  

signature="$CHICAGO$"

AdvancedINF=2.0

[Add.Code]

ActivexDemo.ocx=ActivexDemo.ocx

demo.inf = demo.inf

[ActivexDemo.ocx]

file-win32-x86=thiscab  

RegisterServer=yes  

clsid={5DCFE3E9-C435-407D-AC1F-5205091A64F2}  
 
DestDir=11  

FileVersion=1,0,0,1

[demo.inf]
file=thiscab 


------解决方案--------------------------------------------------------
“cabarc -s 6144 n demo.cab demo.inf” 不要“atl90.dll Polygon.dll”
------解决方案--------------------------------------------------------
好吧，我错了，这样没有给dll签名到运行控件时会提示未验证发行者，还是有可能给杀毒软件灭掉~ 找出你ocx要用到的dll，也一同签名了~ 我也是在学，加勒个油~
