Hello ,
I am trying to update my exisiting application thru MFC feature pack .
I have done all prerequisite for that.
like Change the base classes (CMDIFrameWnd to CMDIFrameWndEx etc.)from and other initialization .
But i am getting stack overflow while doing CoCreateInstanceEx ..

MULTI_QI multi_qi[1];
	ZeroMemory(multi_qi, sizeof(multi_qi));
	multi_qi[0].pIID = &__uuidof(IEPPoolingServer);    
	multi_qi[0].pItf = NULL;
	multi_qi[0].hr = 0;
	hRet = ::CoCreateInstanceEx(__uuidof(PoolServer), 0, CLSCTX_SERVER, pServerInfo, 1, multi_qi);

Call stack.
