Executing plug-in through COM object

Question

Hello,
I have tried  to create plugin with ATL COM object for  possibility execute the function into plug-in from my  application. And have got Runtime Exception which  refer to red line in code below ("Expression: gCoreVersion>=CoreHFT_VERSION_2")
The next list is my C# code for invoke function RunReplacen for COM coclass ConnectorToAcrobat
     Type type = Type.GetTypeFromCLSID(guid);
     ConnectorToAcrobat connector = (ConnectorToAcrobat) Activator.CreateInstance(type);
     connector.RunReplace(@"Part1.u3d");
The next C++ code  is part of COM object
#ifndef MAC_PLATFORM
#include "PIHeaders.h"
#endif
STDMETHODIMP CConnectorToAcrobat::RunReplace(BSTR filePathToU3D)
      char myPath[MAX_PATH];
      wcstombs(myPath, filePathToU3D, MAX_PATH);
      ASAtom pathType = ASAtomFromString("Cstring");
     // Function of plug-in
      CreatePDFWith3DAnnotation(&name);
      return S_OK;
What is wrong? How can I workarround this problem?

No, plugin and COM object it is a one  solid file.
Anyway, I've faced with new problems.  The  AVDocOpenFromFile(ASPathName , ASFileSys , ASText )  function  works perfectly,  but if file doesn't containe forms. And when I want to open file with forms I getting crash.
Next, works with multithreading.
ACCB1 ASBool ACCB2 PluginInit(void)
DWORD ThreadID;
HANDLE hThread = CreateThread(0,0, ThreadProc, NULL, 0, &ThreadID);
return MyPluginSetMenu();
DWORD WINAPI ThreadProc(LPVOID lpParam )
BSTR filePathToU3D = SysAllocString(L"Part1.u3d");
char myPath[MAX_PATH];
wcstombs(myPath, filePathToU3D, MAX_PATH);
ASAtom pathType = ASAtomFromString("Cstring");
//Unhandled exception at 0x56230fa0 in Acrobat.exe: 0xC0000005: Access violation reading location 0x00000044.
ASFileSys fileSys = ASGetDefaultFileSysForPath(pathType, myPath);
ASPathName name = ASFileSysCreatePathName(fileSys, pathType, myPath, NULL);
  CreatePDFWith3DAnnotation(&name);
    return 0;
(this code works fine in one thread)
