在Win7中找不到IEShims.dll

我有一个在VS2010中开发的解决方案.在解决方案中，我得到了一个带有C ++ COM dll的C#winform项目.

在XP上一切正常.
但是，在带有IE8的Win7系统上运行时，发现无法注册dll，因为可以找到IEShims.dll.

我想删除对此dll的引用，但不知道该怎么办.
任何人都可以给我一些想法吗?

谢谢！

I have a solution developed in VS2010. In the solution, I got a C# winform project with a COM dll in C++.

Everything is OK on XP.
But when runing on Win7 system with IE8, it was found that dll could not be registered, because IEShims.dll could be found.

I want to remove the reference to this dll, but don''t know how to do.
Could any body give me some idea??

Thanks!
