*Download link / Code:

Open ScriptLib/PythonLauncher.cpp and search for:

bool CPythonLauncher::RunMemoryTextFile(const char* c_szFileName, UINT uFileSize, const VOID* c_pvFileData)

Replace with:

bool CPythonLauncher::RunMemoryTextFile(const char* c_szFileName, UINT uFileSize, const VOID* c_pvFileData)
{
    const CHAR* c_pcFileData = (const CHAR*)c_pvFileData;
    std::string stConvFileData;
    stConvFileData.reserve(uFileSize);

    for (UINT i = 0; i < uFileSize; ++i)
    {
        if (c_pcFileData[i] != 13)
            stConvFileData += c_pcFileData[i];
    }

    const CHAR* c_pcConvFileData = stConvFileData.c_str();
    PyObject* pCompiledCode = Py_CompileString(c_pcConvFileData, c_szFileName, Py_file_input);//fix
    if (!pCompiledCode)
        return false;
    PyObject* pResult = PyEval_EvalCode((PyCodeObject*)pCompiledCode, m_poDic, m_poDic);
    Py_DECREF(pCompiledCode);//ref c
    if (!pResult)
        return false;

    Py_DECREF(pResult);
    if (Py_FlushLine())
        PyErr_Clear();

    return true;
}
