    can not loat C++Cli dll after migration from C86 to X64 error 0xc06d007e

    After the migration from X86 to X64 we cant load some C++/CLI Dlls anymore. The Project Setting a die not changed really and also the Source is allmost the same ( just some changes form int to __int64 how can i find out what is the exact Problem. Can i check the dll somehow to find out what is wrong with the Dll.

    In our Example the dll i can not load is the is the NmsModelTDotNet.dll

    when i debug i have the following call Stack

    KernelBase.dll!wil:etails:ebugBreak(void) Unknown
    clr.dll!MdaXmlMessage::SendDebugEvent(void) Unknown
    clr.dll!MdaXmlMessage::SendEvent(void) Unknown
    clr.dll!MdaXmlMessage::SendMessage(void) Unknown
    clr.dll!MdaXmlMessage::SendMessagef(int,...) Unknown
    clr.dll!MdaLoaderLock::ReportViolation(struct HINSTANCE__ *) Unknown
    clr.dll!CanRunManagedCodeRare() Unknown
    clr.dll!CorDllMainForThunk(struct HINSTANCE__ *,struct HINSTANCE__ *) Unknown

    [External Code]
    Nms.exe!WinMain(HINSTANCE__ * hInstance, HINSTANCE__ * hPrevInstance, char * lpCmdLine, int nCmdShow) Line 26 C++
    [External Code]

    the ExRawDllMain is the Default

    if (dwReason == DLL_PROCESS_ATTACH)
    // save critical data pointers before running the constructors
    AFX_MODULE_STATE* pModuleState = AfxGetModuleState();
    pModuleState->m_pClassInit = pModuleState->m_classList;
    pModuleState->m_pFactoryInit = pModuleState->m_factoryList;
    pModuleState->m_classList.m_pHead = NULL;
    pModuleState->m_factoryList.m_pHead = NULL;
    return TRUE; // ok

    from MFC

    we do delay load this Dll. But when do not delay load th dlle i have the same problem. It happens just earlier. Whe i try to load the Dll with


    i have the same error

    What is the target (e.g. x86 or x64) of the:
    1) main application
    2) dll you are trying to load

    Are they both being compiled to the same target?
