一、使用regasm.exe将DLL提取出TLB文件
regasm.exe "Tools.HMIBrowserDetector.dll" /tlb
二、使用wix的heat.exe程序
用法如下：
heat file <*.dll> -out <*.wxs>
其中<*.dll>是你用c#编写的activex的dll文件名，<*.wxs>是你要输出的wxs文件名。
heat.exe "Tools.HMIBrowserDetector.dll" -out "Tools.HMIBrowserDetector.dll.wix"
heat.exe "Tools.HMIBrowserDetector.tlb" -out "Tools.HMIBrowserDetector.tlb.wix"
文件生成OK后，打开<*.WXS>文件
1.将其中的<DirectoryRef Id="*">修改成你的目录名，比如<DirectoryRef Id="INSTALLDIR">
2.将<Component Id="*" Guid="PUT-GUID-HERE">中的PUT-GUID-HERE换成你的ACTVIEX的GUID，比如[Guid("3C719C70-EBB6-46A4-B9C5-6A926BDC004C")]的3C719C70-EBB6-46A4-B9C5-6A926BDC004C
最终效果：

3.保存文件，放到WXI安装工程中去
4.修改文件清单wxs，将上面两个ComponentId加入进去，这样文件就会拷贝过去了
